Hello, i am a student interesting in ray intersection. I desires to know how can i intersect a ray with triangulate using gpu. Is there any code abort ray intersection in this project?

Hi, the code you are looking for is in the OpenCL kernels (.cl files) in the following subdirectory: RadeonRays_SDK/RadeonRays/src/kernels/CL/%.cl You will find the code for the ray triangle intersection in common.cl in the function: INLINE float fast_intersect_triangle(ray r, float3 v1, float3 v2, float3 v3, float t_max) The other files (intersect_%.cl) contain the code used for the traversal of the different bounding volume hierarchy variants supported by RadeonRays. One word of warning though: At the moment it looks like AMD likely abandoned this project. So you probably won't get any "official" responses/support from AMD.
