shape representation - particles ?

[Sajjadul Islam]

Hi forum,

Are you implementing the collision detection based on polygons that represent rigid bodies or particles ? 

I am thinking of trying out the following idea described in the gpu gems 3:

Real-Time Rigid Body Simulation on GPUs

http://http.developer.nvidia.com/GPUGems3/gpugems3_ch29.html

Which part of this plugin will help me to understand to implement rigid body simulation where the arbitrary geometry will be represented by particles.

Any references or material is most welcome.

Thanks

Sajjadul

As far as I know, Bullet already supports collision detection on the GPU. I don't know the specifics of how that's done or whether or not it matches the article you cite. For specific questions on how collision detection is done in Bullet, I would recommend posting to the Bullet physics forum.
