WebA BVH is conceptually simple. It’s a tree of bounding volumes, where a bounding volume is usually an axis aligned bounding box that encloses all the surfaces you’ve got underneath it in the tree. An example of a simple BVH class in C++ looks like this: class BVH : public Surface {public: // Constructors and such here BBox bbox; Surface* left; WebIn contrast, Octrees/K-d trees and other space subdivision, divide the space recursively.

WebJun 26, 2024 · This is where the first RTX-Dev enhancement helps resolve the problem. RTX-Dev allows the direction used for occlusion to be selectable by CVar r.RayTracing.OcclusionDirection. Setting this variable to 1 results in it culling front faces rather than back faces, so that it matches the culling done in shadow maps. WebExecution: My ray tracing implementation utilizes Direct3D’s HLSL compute shaders to produce and traverse a Bounded Volume Hierarchy (BVH) on the GPU.

AMD is likely using a stack to perform BVH traversal, and is keeping the stack in the LDS. Existing RT kernels on Navi 21 already have some LDS access instructions, so AMD may already be using the LDS to store a stack of pending nodes to visit.
