WebJun 15, 2024 · The concept of the TLAS (a.k.a. top level BVH) was introduced in article 5 and article 6. The idea is to build and traverse a BVH over BVHs, where each of those BVHs can have a 4×4 matrix transform, for translation, rotation, and scaling. Using the same BVH multiple times but with a different matrix enables instancing. WebOWL builds on the following key concepts: Buffers (realized via CUDA allocated memory), similar to the old Optix 6 optix::Buffertype Buffers can be either device buffers (corresponding to regular cudaMalloc’ed memory), host-pinned memory buffers, or managed memory buffers. cta bus 1995
