Ray traced occlusion culling in point-frag

Postby bouliiii » Tue Nov 29, 2011 9:13 am

Hello all,
I implemented a ray tracing version of the zbuffer occlusing technique. Basically, you compute a small zbuffer and you use it to cull the draw calls you send to your GPU. Pretty simple. I am using the DynBVH technique for that. I wrote a lengthy blog post here:

If you are curious, the code is here:

Cheers,
Ben
