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. WebJun 14, 2024 · You can give OptiX a hint that you prefer a faster BVH build and allow for a possible compromise in traversal performance using …

WebMar 20, 2024 · One solution here is to build acceleration structures for a few key poses upfront, then use the closest match as a source for refit. An experiment guided flow/process is recommended. Use compaction with all static geometry. Compaction is fast and can often reclaim significant amounts of memory.

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.
WebDec 3, 2024 · Likely this is the case because BVH builds are happening in parallel, which quickly exhausts available memory because of temporary build memory required (and has some additional known quirks when memory pooling is active), rather than serialized which does not suffer from that problem.
