I am trying to implement the ray tracing of .obj file for 224 X 172 resolution camera. The Kernel Launch parameters are, 224 threads in X and 172 in Y dimension. I have used the Bounding Box optimization, however for certain scenes, I am getting “Display Driver stopped error: as for a single ray, the entire triangle mesh is checked for intersection. How do I solve this problem?

could u implement this using CUDA

First, thank you for your tutorial , it has been very helpful for me I’m trying to do a simple raytracing (not realtime) with .obj file but I’m a little confused about the camera’s configuration . How can I configure a static camera ?

We are working in a real time ray-tracer using opencl and amd sdk. We are getting some artifacts. like the link below.

Any idea why?

I’m running Windows 7 64-bit.

Could this be a DirectX 9 or 10 thing?

Thanks.
