@Christian Pagot I think it is worth mentioning, that DXR is using Bottom Level Acceleration Structures (BLAS) as well as Top Level Acceleration Structures (TLAS): Figure 3: Overview of raytracing building blocks Figure 4: Overview of raytracing building blocks https://developer.nvidia.com/rtx/raytracing/dxr/DX12-Raytracing-tutorial-Part-1 - please refer ...

First, it is important to observe that there are basically two different "classes" of methods for building accelerations structures for ray tracing: 1) space subdivision methods (e.g. BSP, kD-Tree, Octree, etc.); and 2) object subdivision methods (e.g. BVH). While space subdivison methods work by recursively subdividing the space with planes, ...
