Este es lo mismo que tengo en el otro tutorial que anda por allí, solo en español ;)

Bueno, la escena la pueden descargar de aqui es básicamente una esfera en movimiento, que ademas esta emitiendo particulas. El emitter type es surface y en el tab texture emission attributes, el checkbox de inherit color esta activo. Aqui mismo esta conectada la rampa de color de la esfera y finalmente, particleShape1 tiene opacityPP y rgbPP activos tambien.

The Pirate Bay

2012-01-19T09:50:00.001-08:00

INTERNETS, 18th of January 2012.

PRESS RELEASE, FOR IMMEDIATE RELEASE.

Over a century ago Thomas Edison got the patent for a device which would "do for the eye what the phonograph does forthe ear". He called it the Kinetoscope. He was not only amongst the first to record video, he was also the first personto own the copyright to a motion picture.

Because of Edisons patents for the motion pictures it was close to financially impossible to create motion picturesin the North american east coast. The movie studios therefor relocated to California, and founded what we today callHollywood. The reason was mostly because there was no patent.There was also no copyright to speak of, so the studios could copy old stories and make movies out of them - likeFantasia, one of Disneys biggest hits ever.

So, the whole basis of this industry, that today is screaming about losing control over immaterial rights, is that theycircumvented immaterial rights. They copied (or put in their terminology: "stole") other peoples creative works,without paying for it. They did it in order to make a huge profit. Today, they're all successful and most of thestudios are on the Fortune 500 list of the richest companies in the world. Congratulations - it's all based on beingable to re-use other peoples creative works. And today they hold the rights to what other people create.If you want to get something released, you have to abide to their rules.

The ones they created after circumventingother peoples rules.The reason they are always complainting about "pirates" today is simple. We've done what they did. We circumvented therules they created and created our own. We crushed their monopoly by giving people something more efficient. We allowpeople to have direct communication between eachother, circumventing the profitable middle man, that in some cases takeover 107% of the profits (yes, you pay to work for them).It's all based on the fact that we're competition.

We've proven that their existance in their current form is no longer needed. We're just better than they are.

And the funny part is that our rules are very similar to the founding ideas of the USA. We fight for freedom of speech.We see all people as equal. We believe that the public, not the elite, should rule the nation. We believe that lawsshould be created to serve the public, not the rich corporations.

The Pirate Bay is truly an international community. The team is spread all over the globe - but we've stayed out of theUSA. We have Swedish roots and a swedish friend said this:

The word SOPA means "trash" in Swedish. The word PIPA means "a pipe" in Swedish. This is of course not a coincidence.They want to make the internet inte a one way pipe, with them at the top, shoving trash through the pipe down to therest of us obedient consumers.

The public opinion on this matter is clear. Ask anyone on the street and you'll learn that noone wants to be fed withtrash. Why the US government want the american people to be fed with trash is beyond our imagination but we hope thatyou will stop them, before we all drown.

SOPA can't do anything to stop TPB. Worst case we'll change top level domain from our current .org to one of thehundreds of other names that we already also use. In countries where TPB is blocked, China and Saudi Arabia springs tomind, they block hundreds of our domain names. And did it work? Not really.To fix the "problem of piracy" one should go to the source of the problem. The entertainment industry say they'recreating "culture" but what they really do is stuff like selling overpriced plushy dolls and making 11 year old girlsbecome anorexic. Either from working in the factories that creates the dolls for basically no salary or by watchingmovies and tv shows that make them think that they're fat.

In the great Sid Meiers computer game Civilization you can build Wonders of the world. One of the most powerful onesis Hollywood. With that you control all culture and media in the world. Rupert Murdoch was happy with MySpace and hadno problems with their own piracy until it failed. Now he's complainting that Google is the biggest source of piracyin the world - because he's jealous. He wants to retain his mind control over people and clearly you'd get a morehonest view of things on Wikipedia and Google than on Fox News.

Some facts (years, dates) are probably wrong in this press release. The reason is that we can't access this informationwhen Wikipedia is blacked out. Because of pressure from our failing competitors. We're sorry for that.

Build GCC 4.1.2 | Ubuntu 10.0.4

2012-01-17T15:56:00.000-08:00

So, the stuff I forgot to backup before reinstalling my system (and switching from opensuse to ubuntu) is now evident :)

I need to compile some plugins using gcc 4.1.2 and that means a lot of deb packages to install. Then, when trying to build gcc (make -j 2 bootstrap) there was a recurrent error with makeinfo version.

Long story short: There's a bug which is finally solved here -> http://docwiki.gumstix.org/Buildroot#Makeinfo_.22Missing.22 and now everything is working again!

I'm using ubuntu 10.0.4 (Lucid Lynx) and makeinfo 4.13

Well, that's all for now. Don't forget to check the linux beta/demo of Miarmy!

Small update

2011-12-02T16:19:00.001-08:00

3Delight for Maya was updated today (from 6.0.3 to 6.0.6). There is a lot of things fixed but one new piece added: “Depth of Field” section in the render pass; it contains attributes that control the bokeh (appearance of out-of-focus portions of the image).

Download from here -> http://www.3delight.com/en/index.php?page=3DFM_download

Well, that's all for now. I want to post about render passes and how to insert your own stuff in maya nodes which sometimes can be handy.

soon, reverend...

3Delight for Maya | Physical Sun & Sky

2011-10-20T13:33:00.000-07:00

3Delight for Maya 6.0.3 was released a few days ago.

I'll quote maxime here:

On top of the bug fixes, there is now support for Hypershade networks connected to the render camera's "miEnvironment" plug, and they auto-generate env maps for the GI effects. This allows support for the physical sky Mental Ray node with the Global Illumination effects of the Render Pass. See the "physicalSky.ma" scene in the examples folder for a simple setup showing how this works.

I finally had the chance to set up something more than spheres to show you how it looks (you may even recognize something I've used before):

multi-channel exr & 3delight

2011-10-06T12:12:00.000-07:00

I've been rendering some multi-channel exr files lately using 3delight. Everything is right but the size of every file is around 39 MB each and some sequences are very long. The compression I'm using is zips but I still feel I'm wasting disk space.. really.

A Solution? Using python and nuke to rewrite the files with all channels into a new file. Of course this comes *after* everything is rendered and as a fix.

Reading some posts at vfxtalk and nuke forum, I got this as a base for a more robust script:

cat imageconvert.py

import sys
r = nuke.nodes.Read(file = sys.argv[1])
w = nuke.nodes.Write(file = sys.argv[2])
w.setInput(0, r)
nuke.execute("Write1", 1, 5)

AtomKraft | alpha channel

2011-09-21T15:28:00.000-07:00

So, I'm rendering some scanline stuff in nuke and I thought I should take a look using AtomRender. Is a small project with some geometry but with extreme motion blur (done with vectorBlur nodes). Anyway, I create the AtomRender node, connect it instead of scanline node and... nothing. Well, there was something but wasn't complete.

This is using AtomKraft 0.9.1, by the way. From what I know, there have been lots of things fixed and this is not an issue anymore.

3Delight for Maya | GI effects

2011-09-01T15:31:00.000-07:00

Ok, so you probably know how to get proper GI effects using point clouds, right? If that's not the case or you think it is a bit hard to set up, then you have to take a look at the new GI tab in 3Delight for Maya 6.0.

3Delight for Maya 6.0.0

2011-08-31T16:36:00.000-07:00

Singapore – August 30th, 2011 – DNA Research announces 3Delight for Maya 6.0, the latest major evolution of our fully integrated rendering plug-in for Autodesk Maya.

Starting immediately, 3Delight for Maya will be available as a package with a new entry level pricing. This package is aimed at artists as well as small to medium sized studio who wish to work with a fast, robust, production-strength renderer that is totally integrated into Maya.

This new release improves usability and user-friendliness through improving UI improved user experience in our Maya plug-in and includes many performance and quality improvements in the core renderer.

Highlights of version 6.0

A new "Global Illumination" UI - This tab allows for an easy control of global illumination settings, for both ray-traced and point-based algorithms and no furthershader programming is necessary. Multi-bounce global illumination effects are easilycomputed using photon mapping.

Rendering Optimizations - Ray-tracing and global illumination are faster for reflections, refractions, occlusion and shadows. Users can expect accelertion up to 50% in shading intensive renders.

Minimal Passes and Passes Templates - This feature presents the user with a simple, uncluttered, render pass interface. Users can add features as needed for maximum sability. Such passes can then be organized in templates for rapid access.

More efficient Relationship Editor - Large scenes are no longer a problem for the relation-ship editor. Scenes with thousands of nodes and assignments handle seamlessly.

Faster scene parsing - A "scene caching" feature through RIB fragments further improves rendering performance, especially the loading time.

UI Improvements - Many all-around improvements to the user interface increase productivity.

Latest Maya support - Autodesk Maya 2012 is supported.

Read the press release for further details or the release notes for a complete list of new features and performance improvements.

And there's a new pricing scheme as well, go get your free license!

3Delight for Maya | renderman code nodes & linear stuff

2011-08-23T16:07:00.000-07:00

Ok, I was getting ready for next tutorial-like post but I thought I should take another read on some posts @ 3delight's forum.

Basically, using the next function in renderman code nodes and connecting your maya file node in the input will result in a "linearized" image, right?


color sRGBToLinear( color inCol )

	{

	 float _r,_g,_b = 0;

	 if( comp(inCol,0) < 0.04045 ) { _r = comp(inCol,0)/12.92; }else{ _r = pow( (comp(inCol,0)+0.055)/1.055, 2.4 ); } 	  

	 if( comp(inCol,1) < 0.04045 ) { _g = comp(inCol,1)/12.92; }else{ _g = pow( (comp(inCol,1)+0.055)/1.055, 2.4 ); } 	  

	 if( comp(inCol,2) < 0.04045 ) { _b = comp(inCol,2)/12.92; }else{ _b = pow( (comp(inCol,2)+0.055)/1.055, 2.4 ); }    	  



	 return color(_r,_g,_b); 

	}

Well, it won't. There's a file called DL_globals.mel in your 3delight installation which will perform a tdlmake call on every file node. This means we'll get a prefiltered image from a srgb texture map and this is incorrect. A solution? Well, we could simply edit that file (line 3269) from


  string $cmd = "tdlmake -newer -mode periodic ";


  string $cmd = "tdlmake -colorspace srgb -newer -mode periodic ";

But we have some exr and hdr files from time to time. Then we should check if the file is in any of those formats (linear) and modify that tdlmake call. Or we could simply use tdlmake in terminal on the textures to be used, outside maya. If we have lots of files, we can use a batch script (zsh works fine).

Long story short: This can mess up with the way you're rendering and that's why it is complicated to find the perfect workflow here, in the "web". From this point, it is better to assume everything read into maya is in the correct color space.

That function, by the way, is from Nick Deboar's shaders posted here: http://www.3delight.com/en/modules/PunBB/viewtopic.php?id=3010

I'll fix some scenes and will get back with something useful (yeah, probably has been too much garbage around here for a couple of months).

I usually wait for the change on the maya window and splash screen only, so in the end there's always more than that ;) (except for 2010 I think...) but this time, there's something I'm more than happy to read:

mental ray Rendering
mental ray support for compressed .tif files
mental ray for Maya now supports input of LZW compressed .tif texture files.

It was about time.

What to do if nodes in your Nuke script go missing and you get a warning similar to can't read "C7696e510": no such variable?

Hay algunos trucos para renderear un pase similar a motion vectors, pero por el tiempo que teniamos no era posible hacer pruebas para ver que tan exacto era...

Esta vez una serie de directional blurs en compuesto fue la opción, pero creo que la próxima vez veremos a Floyd (http://www.jupiter-jazz.com/floyd) en acción :)

I have the compiled dso to be used with 3delight but I haven't tested more so I'll upload it when I'm sure it is working :)

updates & more

2010-12-17T13:47:00.000-08:00

Well, has been a busy month even when we@pandaka didn't wanted it to be. First, we finished some shots for another movie (Viento en Contra). After that we tried to install fedora 14 as base system but it's waay more tricky to set up and after trying CentOS 5.5, RHEL 5.5, Ubuntu 10.10 as well, we ended up with OpenSuSE 10.3 :)

Maybe the wacom intuos 4 and the pressure thing in Nuke, Maya and Mari was the most urgent part. Sadly, Qt and those programs mentioned above are stuck with older (read: supported) distros which still use xorg.conf as a way to know there's a wacom plugged in the workstation. Anyway, after compiling the driver and setting up xinitrc everything was working as expected (pressure in Maya has been easy to set up).

Well, while everything gets fixed on the developers side, it was important to start the next year with a clean and fresh install. That's important for me because on my previous system I had gcc412 compiled, then some plugins for maya with wrong include files (read: maya can load the plugin but will crash). My intention is to keep a space with custom compiled libraries and small applications but with proper files (yeahh.. cortex, here I come!).

As a sidenote, if you're trying to compile gcc4.x and get errors on the second pass (specifically using the maya documentation for linux compiler) about fastjar not finding makeinfo even when there's makeinfo installed on the system, take a look again on the requirements, then if everything is in place but the makeinfo problem persist, take a look at the Makefile (in gcc-build). Look for the string "Makeinfo=". The segment looks like this:

# Flags to pass to stage2 and later makes. They are defined
# here so that they can be overridden by Makefile fragments.
BOOT_CFLAGS= -g -O2

BISON = bison
YACC = bison -y
FLEX = flex
LEX = flex
M4 = m4
MAKEINFO = makeinfo
EXPECT = expect
RUNTEST = runtest

Well, make sure "MAKEINFO=" is set to "makeinfo". I had the name of the sources directory and "missing" on the end. After fixing that one line everything was built without errors.

I started checking the files after reading this: http://www.linuxquestions.org/questions/linux-software-2/building-gcc-4-1-x-how-to-fix-688209/

Well, that's it. Now back to selecting stuff for the demo reel :D

"Alta" Velocidad

Estando hasta el huevo del internet caro y lento de Telmex (Infinitum "Acerques" 2Mbps de bajada y 30 kbps de subida), estuvimos revisando opciones: Tangentte, Axtel y Iusacell (Infinitum no supera ~750kbps por $2000MX!! y cablevision tiene muy mala reputación).

Axtel no tiene cobertura en mi área, asi que solo queda Iusacell y tangentte:

Proveedor precio mensual velocidad subida velocidad bajada
---------------
Iusacell $999.00 1 Mbps 10 Mbps
tangentte $766.00 3 Mbps 6 Mbps

Iusacell instala roseta de fibra óptica y no se si es porque nací en los 80s pero si no veo cables no me da confianza (la misma, al menos). El caso es que por precio y velocidad de subida, tangentte es la opción, finalmente y como dicen por alli, peor estabamos!

Cuando finalmente quiero ver cuando vienen a instalar las antenas y todo el papeleo, no me contestan correos y por telefono me dejan esperando. Investigando, leo que:

"Entretanto Bestel fue adquirida en 2007 por Televisa y al ponerse en contacto James con la nueva administración, la situación se complicó: no sólo exigieron los pagos atrasados (que rebasaban millones de dólares), sino que le informaron que si quería rentar, vender o usar su fibra óptica como garantía, requería la aprobación de Bestel."

El link es este: http://blogs.cnnexpansion.com/informacion-privilegiada/?p=2072

Y al parecer, la unica opción es Iusacell. Ahh, en los comentarios se habla un poco mas del problema.. la verdad es deprimente el panorama. Apenas unos meses atras se leia esto: http://193.47.76.62/eldebate/Articulos/ArticuloGeneral.asp?IdArt=9356051&IdCat=6110.

IF YOU CROSS THE IRANIAN BORDER ILLEGALLY,
YOU ARE DETAINED INDEFINITELY.

IF YOU CROSS THE AFGHAN BORDER ILLEGALLY,

A LOBBYIST IN WASHINGTON WITH BILLIONS OF DOLLARS WORTH OF PUBLIC DOCUMENTS PRINTED IN YOUR LANGUAGE.
THE RIGHT TO CARRY YOUR COUNTRY'S FLAG, WHILE YOU PROTEST THAT YOU DON'T GET ENOUGH RESPECT.
AND, IN MANY INSTANCES, YOU CAN VOTE.

I think he's right. He was born.. where? Israel? Oh, yeah. Then move to USA and get a job, drivers license and blah blah, until KISS. Then age strikes and poof: The guy becomes an ass. Then tries to sue everbody downloading the copy of the copy of what KISS used to be (30+ years ago). That's sad. Personally I used to be a fan of those times but I guess not anymore. Maybe Vinnie Vincent was right after all.

He also seems to forget about Nick and the whole steal-some-drawings-from-somebody-else-in-the-other-side-of-the-world thing. I hope he can learn something positive though (besides trying to get money squeezing rocks).

Anyway.. saw KISS a few weeks back and the opening band (the ENVY) sucked balls big time. I didn't had enough coins to throw :(

ok, enough. No mas.

co shaders

2010-08-20T09:35:00.001-07:00

After some weeks of hard work, the monkeys @ pandaka are finally wrapping up sequences for delivery! ^_^

Since more projects are starting now, it's time to update&test&deploy||deprecate some stuff around. And since more pieces are being added, it was a nice opportunity to start with co shaders:

// class based shader calling a co-shader
class simple_layer(
float displacement_weight = 1;
string displacement_map = "";

shader co_shader_dummy1 = null;
shader co_shader_dummy2 = null;

)
{
// displacement method
public void displacement (output point P; output normal N)
{
if (displacement_map != "" && displacement_weight != 0)
{
float _disp = displacement_weight * float texture (displacement_map, s, t);
P += _disp * normalize (N);
N = calculatenormal (P);
}
}

normal Nn = normalize(N);
vector V = normalize(-I);
// surface method
public void surface (output color Ci, Oi)
{

uniform float i = 0;

shader co_shader_ [] = getshaders ();
for (i = 0; i < 1 ="=">diffuse(Nn, P);
}

if (co_shader_ [i] != null && 1 == hasmethod (co_shader_ [i], "occlusion"))
{
occlusion variable *= co_shader_ [i]->occlusion(Nn, P);
}
// more inputs here...
}

Oi = Os;
Ci = composite stuff
Ci *= Oi;
}
}

So, it's a modular way to connect stuff... you already know how they work but this is great if you think in the possibilities within maya or any other high end application ;) And I'm fresh to classes and the idea of clean, organized and reusable pieces of code in a single shader is just exciting (not like my all-in-one+patches shader)...

edit: I hate the lack of code tags.

cortex-5.6.0

2010-07-28T16:58:00.000-07:00

You probably know cortex http://code.google.com/p/cortex-vfx/

I remember I read something about it a few weeks ago, but I wasn't really aware of what could I do with it (since I'm not a python/c++ guy). Well, today I was reading a bit more and suddenly I feel like I need to understand that stuff.

After downloading the code and adding a few more devel packages (or adding the existing ones to the path) I finally got the stuff compiled.

Now, after loading the plugin, I try to do the examples but seems like either those examples are old or the cortex code isn't ready for the changes in maya 2011. I feel a bit like when I tried to use liquid a few years ago (yes, *years*).

So, if you happen to understand a bit more on IECoreMaya and its examples, I'd be interested in some help :)

Soy gran fan del trabajo que ha hecho /*jupiter jazz*/ con 3delight. Y hoy estan integrando un elemento mas: Nuke.

Un flujo mas o menos normal de trabajo consiste en hacer bake de occlusion o difuso y asignarlos a geometria exportada de maya como fbx en nuke y renderear directo al compuesto (usando scanline render).

Con AtomKraft es posible eliminar la parte de baking a texturas porque estaria rendereandose con 3delight directamente al compuesto dentro de nuke!

free VFX tracking markers!!

2010-06-11T12:38:00.000-07:00

No tracking markers makes little bunny sad.

HOw many times have you heard about bad tracking markers in a shot? Or maybe non tracking markers at all? These shots can be hard to track and solve :(

Well, this may be of your interest:

Now you can place points just where you need them! Download the image, cut along the dotted line and paste the markers in the zones where your favourite application can see it!

IF that's not enough fun for you, you can download the cat pawns pattern for your tracking markers! Cut'em, Paint'em and Paste'em where you need'em! No more sad tracking applications trying to find where the fuc*k the points are! It's super effective!

^_^

supes may have a different opinion tho :p

2010-06-11T06:17:00.000-07:00

Check this out http://petershipkov.com/development/SOuP/SOuP.htm (thanks to Peter Shipkov).

"SOuP is a set of plug-ins that extend the procedural (and other) capabilities of Maya.

As you probably know Maya needs more (sophisticated) "live" data generators and modifiers that operate on components lists, objects groups and point attributes. This imposes a lot of limitations when doing more involving things like complex effects, advanced characters and actually quite often geometry manipulations."

de linear a srgb & viceversa

2010-04-27T13:51:00.000-07:00

Contrario a otros espacios de color basados en RGB, el sRGB no puede expresarse con un valor numerico absoluto (gamma=1.0 en secciones cercanas al negro y otro valor en otras zonas).

Basicamente es entender esto: http://renderwonk.com/blog/index.php/archive/adven tures-with-gamma-correct-rendering/ que es lo mismo que esto otro: http://www.harrybard ak.co.uk/sRGB.htm e implementar una solucion en 3delight. mental ray for maya incluye lens shaders y un nodo en las opciones de render para convertir el espacio de color de los mapas que se usan.

Pero antes de hablar de mapas, hablemos de la iluminacion. Comunmente, las luces que utilizamos no tienen decay porque nunca funciona correctamente. El problema no esta en las luces, sino en la interpretacion que tenemos del resultado. Lo que obtenemos por default es una salida en espacio de color lineal (linear colorspace). Esto no es incorrecto, pero aun falta commpensar la salida, es decir, convertir el resultado al espacio de color que tenemos en el display (monitor, con pc un gamma de 2.2).

En el primer link lo manejan como 1+1=3. Pero si a ese resultado lo desplegamos como sRGB, veremos los resultados "correctamente". En 3delight, eso se hace a traves del i-display.

Una vez que hacemos esto, lo que veremos sera una imagen lineal pero en el espacio de color correcto.

Tenemos esta imagen. A la izquierda es la salida sin modificar nada en el display. A la derecha, ya tenemos lo que necesitamos ver.

Ahora, veamos el caso en un ejemplo mas claro:

En este punto solo hemos modificado el display a gamma 2.2.

Pero que pasa con un mapa de color? generalmente vamos a tener mapas de color de 8 bits. Estos se pintaron en photoshop o en bodypaint o zbrush. Se encuentran en espacio sRGB, asi que si los inclumos en nuestros renders con el i-display gamma=2.2, vamos a encontrar la textura "deslavada" (mezcla de espacios de color).

Una solucion es modificar el gamma de las imagenes a 0.4545, pero 8 bits no son suficientes para ajustar los valores oscuros y esto crearia banding en los renders. Si usamos tdlmake para optimizar las imagenes, podemos especificar el espacio de color (tdlmake -colorspace srgb in.tif out.tdl), pero podemos tambien solucionarlo por shading.

Para esto, necesitamos crear un par de funciones:

//decode from sRGB luma to linear light
float sRGB_f(float f)
{
   float lin;
   if(f <= 0.04045)
      lin = f / 12.92;
   else
      lin = pow ((f + 0.055) / 1.055, 2.4);
   return lin;
}

color sRGB(color c)
{
   color d;
   d[0] = sRGB_f (c[0]);
   d[1] = sRGB_f (c[1]);
   d[2] = sRGB_f (c[2]);
   return d;
}

Con esto tenemos "linearizada" la entrada de color, pero como lo integramos al shading?. Si por ejemplo tenemos este shader (txtplastic.sl en 3delight/shaders/src):
/* Copyrighted Pixar 1989 */
/* From the RenderMan Companion p.374 */
/* Listing 16.29 Plastic surface shader using a texture map*/

/*
* txtplastic(): version of plastic() shader using an optional texture map
*/

surface txtplastic(
float Ks = .5,
Kd = .5,
Ka = 1,
roughness = .1;
color specularcolor = 1;
string mapname = "")
{
point Nf = faceforward(normalize(N), I );

if( mapname != "" )
Ci = color texture( mapname );/* Use s and t */
else
Ci = Cs;

Oi = Os;
Ci = Os * ( Ci *
(Ka*ambient() + Kd*diffuse(Nf))
+ specularcolor * Ks * specular(Nf, normalize( -I ), roughness) );
}
Solo necesitamos incluir las funciones y llamar sRGB (color c) justo antes de asignar Oi:

/* Copyrighted Pixar 1989 */
/* From the RenderMan Companion p.374 */
/* Listing 16.29 Plastic surface shader using a texture map*/

/*
* txtplastic(): version of plastic() shader using an optional texture map
*/
//decode from sRGB luma to linear light
float sRGB_f(float f)
{
float lin;
if(f <= 0.04045)
lin = f / 12.92;
else
lin = pow ((f + 0.055) / 1.055, 2.4);
return lin;
}

color sRGB(color c)
{
color d;
d[0] = sRGB_f (c[0]);
d[1] = sRGB_f (c[1]);
d[2] = sRGB_f (c[2]);
return d;
}

surface txtplastic(
float Ks = .5,
Kd = .5,
Ka = 1,
roughness = .1;
color specularcolor = 1;
string mapname = "")
{
point Nf = faceforward(normalize(N), I );

if( mapname != "" )
Ci = sRGB (color texture( mapname ));/* Use s and t */
else
Ci = Cs;

Oi = Os;
Ci = Os * ( Ci *
(Ka*ambient() + Kd*diffuse(Nf))
+ specularcolor * Ks * specular(Nf, normalize( -I ), roughness) );
}
Asi, con el ejemplo de las calaveras, podemos ver la diferencia entre visualizar linear color space y su version en sRGB.

Finalmente, la ventaja de usar una funcion a nivel de shading es q ue s i usamos AOVs, la salida de color no se altera, por lo que si se esta trabajando c o mpuesto en, digamos Nuke, al momento de cargar las imagenes podemos ver if icar el espacio de color. Por default, el viewer es sRGB, las imagenes de 8 bi ts s on sRGB y de 32 bits son linear. L a s de 16 bits son sRGB, pero lo podemos modificar en el nodo del Read.

Como lo simplifica SeB en el foro de 3delight: "If I understand it well he did a gamma correct of 2.2 and use a gamma of .455 for textures color to fix the wash out".

I was about to make Yakimeshi for lunch, but then I found a can of coconut milk (leite de coco) that was lost in the back of the paper bags compartment. So I decided to switch what was in the wok (broccoli, chauchas, etc) and added the coconut milk instead of rice and soy.

A pinch of curry powder, a pinch of salt, a pinch of garlic and more curry powder. Then some garam masala (home made ;) ) and black pepper.

Well, in teh end everything was just right. The steamed rice was a bit cold because It wasn't supposed to be served like that but didn't feel too cold either. The sriracha sauce was in charge of that anyway :)

3Delight 9.0 /3Delight For Maya 5.0

2009-12-10T18:30:00.000-08:00

Ya salio la nueva version de 3Delight!!

Changelog
http://www.3delight.com/en/modules/d...ight_changelog

Descarguen de aqui:
http://www.3delight.com/en/index.php/download/step_1

Ya imaginaba que iba a salir estos dias, ademas de que houdini anunció también soporte para la versión 9!!

Pensaba postear un par de cosas en el ftp, pero aplus.net es una mierda del tamaño de un lobo feroz >_<

Edit: Esta es la lista de cosas oficial para este release
3DELIGHT 9.0 AND 3DELIGHT FOR MAYA 5.0
============================
December 2009

New Unlimited-threads License
* A new unlimited-threads license is now available for both
the 3Delight standalone renderer and the 3Delight for Maya
plug-in. Clients that purchased the 8-thread license (and
under yearly support) are automatically upgraded to
unlimited-threads. The 8-thread license will no longer be
available, but the 4-threads and 2-threads will continue to
be available at a reduced pricing.

3Delight For Maya
* Introducing RIB Fragments: a user-friendly and flexible way
of creating and managing RIB archives. This feature is
useful to accelerate re-renders.

* The display drivers UI has been improved and simplified
making it easier to manage and visualize output variables
(AOVs). "Primary Displays" and "Secondary Displays" have
been collapsed into the same UI.

* Major performance improvements to the 3Delight Relationship
Editor which make it responsive even with very large scenes.

* Improved UI in the 3Delight Relationship Editor by using
distinctive icons for different shaders and attributes.

* Added support for many useful Hypershade nodes, most
importantly: misss shaders, car paint, metallic paint,
glossy reflection and glossy refraction.

* Scene parsing optimizations reduce RIB output time by 20%.

* It is now possible to render Shave and a Haircut nodes
without loading the 3dfmShave plug-in: 3Delight for Maya
automatically uses Shave plug-in's RIB export function in
that case.

* Maya sprite particles can now be rendered as "volumes" for
correct shadowing.

* Maya fluids implementation enters a beta stage. All current
limitations are listed in the user's manual in the
Rendering Guidelines chapter.

* Added Maya 2010 support and dropped Maya 8.0 support.

3Delight Features
* Introducing multi-camera rendering. This features enables
the output of many camera views from a single render. This
functionality is especially useful for stereo rendering as
it saves rendering time.

* Improvements to point-based occlusion quality: concave
corners are rendered more accurately.

* The subsurface shadeop can proceed from a point-cloud file.
This can save a potentially costly pre-processing step when
rendering sequences.

* Billboard particles can now be rendered with a "thickness"
for correct shadow casting.

* Network caching, a feature unique to 3Delight, is now
available on Windows systems.

* Added detailed memory statistics to 3Delight to better
track memory usage.

3Delight Performance
* Improved performance of occlusion() and indirectdiffuse()
shadeops when rendering dense meshes. Speedups can reach
200%.

* Improved multi-threading performance on scenes containing
procedural geometry (such as delayed read archives).
Procedurals are now allowed to execute in parallel which
can lead to speed improvements linear to the number of
threads used.

* Accelerated point-based occlusion as it now supports the
"irradiance shadingrate". Speedups with default settings
are in the range of 200% to 300%.

* Improved multi-threading performance and memory consumption
of subsurface scattering algorithm.

* Improved deep shadow map creation performance. On large
shadow maps, performance increases linearly with the number
of cores. Temporary disk space usage during DSM creation
has been reduced three-folds.

* A new memory allocation scheme in the ray-tracer
significantly lowers memory consumption when rendering
object: only one object instance is kept in memory at any
time. This feature is enabled through a special variable.

* Improved point-cloud loading time. This has a positive
performance impact on effects such as point-based occlusion
and color bleeding.

Shader Compiler
* RSL 2.0 improvements including resizeable arrays, better
supports for shader classes and more efficient execution.

Pipeline & API
* Introducing the "VolumeTracer" API. This RSL plug-in allows
user to easily write volume renderers.

* The "Sx" shader evaluation API is now embedded with the
3Delight library (takes a single 3Delight license when
used).

* Added "Implicit Field" plug-in support (extension to the
`RiBlobby' primitive).

* Display drivers can now access 3Delight's deep frame buffer
which provides the list of visible surfaces for each pixel
sample.

* Added new entries to the Ptc API and fixed compatibility
issues.

* `RiNuCurves' now support vertex normals.

simples extras

2009-11-25T17:12:00.000-08:00

Ayer estaba revisando algunos scripts. Habia cambios que hacer en algunos procedimientos que cambiaron en 3delight 8.0.43 y es mejor ahora que mas adelante. O lo que es igual: justamente (como finalmente terminé de leer "Hablemos de Kevin", de Lionel Shriver, me lleve mi libro de "Movimiento Perpetuo", de Augusto Monterroso, qepd).

Bueno, la cosa es que necesito estandarizar mis variables de salida, ver si puedo entender coshaders y actualizar los shaders que mas uso, porque ha sido parche sobre parche desde abril 2009.

Pero eso no es lo que queria decir. Mas bien, me di un tiempo para revisar mis salidas extra, las del monton y que no siempre uso. Una de ellas es normales, obviamente, pero de las menos usuales es uv (st) y Point.

Tambien falta utilizar ifdef por si no hay AOVs :/

/* simple_utils */
surface simple_utils (
float salida = 3.0;
output varying color renderAOV_normal = 0.0;
output varying color renderAOV_point = 0.0;
output varying color renderAOV_uv = 0.0;
)
{
normal Nn = normalize(N);
vector In = normalize(I);
extern point P;
Ci = color (mix(0,1,s),0,mix(0,1,t));
if (salida == 1.0)
Ci = color (ntransform ("world", normalize (N)));
else if (salida == 2.0)
Ci = color (P);

p.d. La cirugía de JC (ahora Vanessa) salio perfecta! rofllolzzers. En realidad le retiraron un tumor de la zona mandibular izquierda.

fur

2009-11-21T14:02:00.000-08:00

Despues de un rato de no colgar nada por aqui, los actualizo:

* Finalmente estamos organizando archivos que habia en los discos de backup. Mas de 1.5 teras de datos (cerca de 350GB de bootlegs :p).

* Estamos estructurando el reel.

* Ya hay base para pagina web.

Mientras pasa eso, estoy actualizando alguno scripts y shaders. En 3delight 8.5.42:"Added several primitive variables available for output when rendering Maya Fur.". Esto significó retomar el shading de fur, modificar el código que estaba usando (http://www.185vfx.com/resources/coursenotes.html) e implementar self shadows con atenuación, mapas de color sin bakear el FurDescription de maya y como paso siguiente es leer occlusion y radiance de la superficie donde tenemos la raiz de cada pelo.

Estos son algunos renders de pruebas. Aun falta añadirle algo de opciones y probarlo en movimiento. Luego posteare algo acerca de los tiempos de render.

Calavera

2009-11-11T11:45:00.001-08:00

Este es un proyecto que hicimos muy rapidamente. Para un concurso de edumac (una escuela de artes digitales).

El tema era la calavera mexicana tipica de este dia de muertos. Y la imagen de la derecha es con la que participamos jc y yo (jc modelado/sculpting) y yo render.

El resto de los participantes esta en http://www.flickr.com/groups/concurso-calavera/pool/

Por cierto, no tiene nada que ver pero pense que seria interesante para todos los que puedan pasar por aqui y leer lo que soñé: Resulta que estaba en medio de una fiesta con unos cuates en el lugar donde crecí (en Colima). Era ya de madrugada en esa fiesta y en un ataque de tos, termine con una flema colgando de la boca. Total que empece a jalar la flema con las dos manos y no se veia que terminara!. El punto donde me detuve fue cuando vi que de la flema venia colgando parte de mis tripas y una cosa parecida a un riñon (los vi en un programa del discovery).

Al ver mis tripas en el suelo, empece a acomodarlas en mi brazo izquierdo (como si fuera un tendedero o un largo cable ethernet de emergencia) y fui por ayuda. Lo malo es que la mayoria andaba ya con muchas copas encima y nadie me hacia caso. Me encabroné y fui por una sabanita para cubrir mis cosas y espere un taxi. Los dos taxis que pasaron tenian poco espacio y yo no cabia con mis tripas (y ni modo de dejarlas en la cajuela).

Ya cuando me habia acostumbrado a la situacion, llegue a un hospital, a la zona de emergencias, pero me dijeron que esperara, porque el servicio empezaba a las 3pm (y eran las 7am!!!).

El despertador (de la vida real) sonó y desperte cuando en mi sueño esperaba pacientemente sentado con mis tripas en un brazo cubiertas con un mantel.

Y eso es solo parte del sueño, tambien estuve caminando por Austin cargando a Gato, visitando a Alvaro y su monton de perros. Al parecer estaba desayunando una copa de vino blanco con un plato de frijoles con queso.

Bueno, es todo. Es de los sueños mas normales que he tenido. Ja!.

Deathfall is back!

Han pasado mas dias de lo que planeaba para actualizar aqui, pero he estado ocupado. De cualquier forma, no queria dejar pasar esto:

Nos vemos ahi ;)

Anuncio

2009-09-04T15:05:00.000-07:00

Hoy compartimos (JC & un servidor) con ustedes algo que nos motiva a seguir creciendo no solo en el ámbito profesional, sino tambien en el personal: Hemos decidido separarnos de nuestro actual empleo en http://www.thefxshop.com y trabajar de manera independiente.

Al igual que en http://www.clusterstudio.com anteriormente, FX Shop fue un campo de aprendizaje enorme. Significó nuevos retos, nuevos amigos, oportunidades de acción que son gran parte de lo que somos ahora y que sin duda fundamentan mucho de esta decisión.

¡Hasta Pronto!

Actualización

2009-09-02T10:43:00.000-07:00

Bueno, después de algunos pendientes, puedo actualizar aqui. Y después de que la tormenta se va, viene la calma y el recuento de los daños. :)

Un pipeline o flujo ideal siempre cambia, por mas mínimo que sea, para mejorar. Y puede ser desde una implementación a nivel hardware (todos los nodos conectados al servidor por ocfs2: no más autofs/nfs4) o un cambio en alguna parte del software (digamos, un script de bash para convertir sl a sdl en linux/windows con paths acordes al sistema) o simplemente a nivel usuario: cuanta agua necesita la cafetera para 4 tazas de té sin que quedes corto o no quede agua en la cafetera para que se evapore con el calor restante justo antes de apagarla.

Bueno, al final es regresar a lo mas simple, ver que tan eficiente, útil, compacto, elegante y portable es en relación a lo que puede llegar a ser. El tiempo necesario para llegar a ese punto "ideal" es lo de menos, finalmente, vendrán nuevas tormentas, trayendo consigo modificaciones simples que nos harán exclamar "aahh claro, eso era así".

¿El punto? El punto es que es el momento de regresar a lo mas simple, ver que tan eficiente, útil, compacto, elegante y portable es.

Un ejemplo:

/* simple_ptc_sss */

surface simple_ptc_subsurface(
string bakefile = "";
color albedo = color (0.830, 0.791, 0.753);
color dmfp = color (8.51, 5.57, 3.95);
float ior = 1.5;
float scale = 1.0;
)
{
normal Nf = transform ("world", "camera", normalize(normal N));
color sss = 0;
point Pcam = transform ("world", "camera", point P);

sss = subsurface (Pcam, Nf,
"filename", bakefile,
"diffusemeanfreepath", dmfp,
"albedo", albedo,
"scale", scale,
"ior", ior);
Ci = sss;
}

Mas detalles el viernes ;)

¡chan chan chanchaaaaannnnnn!

SAMAEL & raytraced reflections / ptc

2009-08-24T18:20:00.000-07:00

¡SAMAEL de regreso en México!
19/Septiembre/2009 | ¿quien se apunta?.. yo ya tengo mi boleto :p

Y en cuanto a raytraced reflections, con 3delight 8.5.24, exportando un point cloud para leer "radiance", olvidé desactivar raytraced reflections. El resultado es que todo se transforma en luces aleatorias afectando difuso, el propio valor de radiance y color. De soporte me comentaron que no era necesario ni siquiera tener specular (de ser posible). Así que ustedes no lo olviden: no raytraced reflections cuando "beikien" point clouds.

glossy reflections

2009-08-17T13:07:00.000-07:00

Después de un proyecto mas en el estudio, estoy modificando algunos shaders que tenía pendientes. Principalmente convertir la sección de point clouds a un attributo mas, en lugar de a través de luces ambientales :)

Y parte de esa modificación incluye en algunas partes glossy reflections usando el mismo point cloud que uso para radiance.

Este código esta en el foro de 3delight, y se basa en indirectdiffuse con un ángulo de menos de 90 grados.

surface
ptc_glossyReflection (
string filename = "", sides = "front";
float clampbleeding = 1, sortbleeding = 1,
maxdist = 10, falloff = 0, falloffmode = 0,
coneangle = 0.2,
samplebase = 0.0, bias = 0.01,
maxsolidangle = 0.1;
)
{
normal Nn = normalize(N);
vector refl = reflect(I, Nn);
color irr;

irr = indirectdiffuse(P, refl, 0, "pointbased", 1, "filename", filename,
"hitsides", sides, "clamp", clampbleeding,
"sortbleeding", sortbleeding,
"maxdist", maxdist, "falloff", falloff,
"falloffmode", falloffmode,
"coneangle", radians (coneangle),
"samplebase", samplebase, "bias", bias,
"maxsolidangle", maxsolidangle);

Ci = irr;
}

Kung Pao

2009-08-11T12:18:00.001-07:00

Hoy para comer, preparamos Kung Pao, con un sobrecito de Asian Gourmet. ¿Las han probado o visto en algun supercito? http://www.asianhomegourmet.com.sg/

Estan bastante buenas. También hemos preparado el Kaang Daeng, y vale la pena. Una vez compramos uno en superama (no recuerdo el nombre) pero como que suavizan un poco las especias para que no peguen y se supone que era un Tikka Masala.

Estos los pueden comprar en la naval, superama, mikasa, entre otros. Y si donde viven no tienen y quieren probar, ya estamos exportando a la hermosa ciudad de Colima. :)

Burocracia

2009-07-28T18:45:00.000-07:00

El domingo pasado, estabamos dando el rol por el Central Market (Dallas, TX) y pensamos en comprar chela importada (bueno, europea); total que tomamos un par de cajas de 24 (:p no, solo eran 2 de 4), fresas, chocolate, pan de centeno y fuimos a la caja express.

Justo cuando pasan las cervezas al lector de código de barras, me piden ID. Saco mi pasaporte y se lo mestro: ¡resulta que en el estado de Texas el pasaporte no es un documento válido para comprar alcohol! Sirve como documento para rentar un auto, entrar a territorio gringo (junto a la visa), cobrar un cheque de 10,000 dólares, entre otras cosas, pero no para comprar cervezas. Lo chistoso es que el sábado, ahi mismo compramos unas cuantas y no hubo ningun problema. Si medio me encabrone un poco porque me parece una idiotez de ley del estado de Texas, y lo mas cagante es que la supervisora me dijo con ojos entrecerrados y barbilla levantada "bueno, puedes usar otro ID del estado".

Después del episodio, nos fuimos al hotel donde aun quedaban algunas cervezas del dia anterior y complementamos con 2 litros de agua y 1 1/2 de vitamin water caliente (hace mucho calor.. es como andar en colima), pero me propuse averiguar si esa ley existia o no: si existe. El estado de Texas no acepta el pasaporte como identificación válida para comprar alcohol.

Eso si, a decir de algunos links en google, pudo haber sido mucho peor: se supone que restaurantes, bares, tienditas y demás tienen prohibido aceptar ese documento, pero solo nos paso una ocasión. Es mas, de haber ido a maryland (creo que es alli), no nos hubieran dejado comprar cerveza porque esta prohibido venderla los domingos antes de mediodia.

La proxima vez, cargare mi acta de nacimiento ;)

ps: La gente es muy amable, la comida es muy buena, la ciudad esta muy chida y realmente no tengo ninguna queja al respecto. Es solo que queria compartir con uds. el incidente. Ah, la inutil licncia de conducir internacional ($990) si puede servir como documento oficial en algunos casos... que ironía.
