Ray tracing intersection triangle
WebApr 10, 2024 · Sure, it just intersects a ray with a triangle to get you a barycentric coordinate. I'm not suggesting ray tracing the Nanite data structure, I'm just suggesting using the instruction to get the barycentric coordinate for the visibility buffer. That's the beauty of compute, flexibility. WebApr 12, 2024 · I expect that the overlapping region should have accumulated color as the ray should hit the overlapping region multiple times. But the final image shows the color for each triangle is not sumed up, which is the same as I uncommented the last line AcceptHitAndEndSearch (); I wonder if my understanding about the anyhit shader is …
