WebBreaking Down Ray Tracing Performance Ray tracing introduces several new workloads for the GPU to perform. The first is determining which triangle in the game scene a ray will intersect. A computationally-intensive technique called Bounding Volume Hierarchy, or BVH, is used to calculate this. WebOne well-known approach for handling dynamic scenes is to essentially recycle the same BVH over and over. The basic idea is to only recalculate the bounding boxes of the nodes according to the new object locations … WebCS 6958 LECTURE 8 TRIANGLES, BVH February 3, 2014 Last Time derived ray-triangle intersection clarification: ray tracing inherently abstract in terms of object specification we … how far down to bury electrical cable
