This is a great little piece of animation exercise made by Will Eades using my rig, Alex. :)

 

 

Alex Rig – Beta

7 Comments | This entry was posted on Dec 13 2012

Hi there!

I’ve been rigging a character in my spare time and I’d like to share it with the animation community.

 

 
Alex’s body has been rigged with Advanced Skeleton and you will find heaps of information and training videos in the Advanced Skeleton home page. The face was custom rigged and I tried to keep it simple and powerful. Lets see what comes out of it. I’ve built a synoptic – or character UI if you will – to make the control selection easier.

 
Donwloads on hold. New version to come soon.

Mesh Slide part 2 – 3d Max SDK + GPU

9 Comments | This entry was posted on Nov 11 2011

As a technical artist, I have worked with Maxscript for a while now and it has been an awesome way to automate repetitive and complex tasks in order to increase the productivity of 3d artists by keeping them focused in the important things. Technical artists make huge effort to keep artists away from boring technical aspects of a production.

However, while Maxscript is quick to learn and to create tools, its use is not suitable for the kind of job that needs high performance and complex calculations. If something like real time mesh deformer is what you need, 3d Max provides you with its lower level software development kit (SDK).

And this is what I wanted to get into to expand my capabilities in the tech art field. Although I have been working with games for a while, the experiments I have been doing with 3d Max SDK are definitely more suitable for VFX on movies production.

…………………

Continuing with my first experiments with 3d Max SDK, in this post I will show some of my progress and publish some more details behind my plugin to be. Please have a look at the following video which contains a compilation of my progress.

Low performance with high poly meshes was one of the problems I faced when creating my CPU version of the plugin. At that point I thought of using fancier octree algorithms to reduce the plugin computation time or caching the mesh deformation but, very curious I am, I chose going another way instead. I decided to use the code I had at that point and try to adapt it to use the power of GPU processing.

For that I worked with OpenCL framework – ATI version of Nvidia Cuda – which demands you to know about video cards architecture. Basically, the advantage of using GPU against CPU is that GPUs have dozens of stream processors – 1120 in my video card case, an ATI 6870 – while CPUs’ standard is something around 1, 2, 4 or 8*. Using all these computing units is not so trivial. It is needed to manage the parallelization of jobs sent to the GPU.

The OpenCL framework only gives support for basic computations though and things like ‘ray intersect mesh’ functions given for free in the 3d Max SDK had to be written in OpenCL (C like) language**.

In the video above I present the result of my experiment where my plugin runs 10x faster in the GPU with higher poly meshes. The greater the number of computations to be made, the greater the difference becomes.

Mesh Slide – 3d Max SDK

This is my first attempt creating a plugin with 3d Max SDK. The work is still in progress but I am pretty happy with the outcome so far. The main deal of this plugin is to create the effect that simulates muscles sliding underneath the skin. My plan now is to polish this plugin, add some more functionalities and post more illustrative examples here soon.

Penadinho – Teaser

Penadinho and his friends are part of a famous Brazilian comic book created by Mauricio de Souza. Mauricio is now investing in new technologies and I had the pleasure to work in a Penadinho’s teaser video as modeler, rigger and animator.
