WebIf you’re looking to do GPU-based ray tracing, the current APIs (DXR, OptiX, and Vulkan ray tracing) will build the BVH for you using improvements over the Karras publications people have mentioned here. In those cases, you mostly need to understand the distinction between top level BVH and bottom level BVH to interact with the API. WebThis avoids recomputing the BVH for geometries that do not have changes in topology but whose vertices are modified (like a simple character animation), and gives up to 40% speedup for BVH building.
