WebApr 7, 2024 · The principal RTX engine provides hardware acceleration for determining the first thing a ray hits in a BVH. According to what I see as a common definition of "ray-casting", that seems to be the definition. I'm not sure what Min/Max ray casting is, but based on your definition here it would probably involve multiple ray traversals in the RTX ... WebRay casting can be performed in a voxel block grid to generate depth and color images at specific view points without extracting the entire surface. ...
