Ambient Occlusion baking into vertex color

Posted by: zhangy on 12/07/2008 07:17 (Read: )
This is a ambient occlusion into vertex color tool.
It's based on nvidia's dynamic ambient occlusion paper. I use cuda to calculate the ao for each vertex. Compare with cpu, using gpu is 22X times faster in this case.

GPU+PFlow: Interesting ?

Posted by: zhangy on 10/03/2008 02:44 (Read: )
Beside work. I'm looking at CUDA(Compute Unified Device Architecture) recently and trying a pflow plugin to use the cuda for acceleration. It works and almost play in real-time for more than 32000 particles with collision!! take a look at this video(you need xvid codec) and rendered mov.
here is collision with a sphere

Download the plugin
I'll post more updates regarding this.

Didn't update the homepage recently. I decided left autodesk end of 2007 and joined EA as senior technicial artist now. I think it's a better position for me, bring me a clearer future path.
Ok. not much updates, here is a better spline vortex plugin for pflow which give you a better control.

ParticleFlow Fluid solver

Posted by: zhangy on 05/03/2007 03:58 (Read: )
This solver is based on Jos Stam's paper "Real-Time Fluid Dynamics for Games". It's a 2D solver and I converted to a 3D solver so the speed is not realtime anymore but still acceptable. I'll post the plugin shortly when it's finished.
Here you will find more Info
