The standard acceleration structure for ray-tracing is the wide BVH, and fast GPU construction of these hierarchies is a key challenge for realtime raytracing. This is especially important for complex dynamic scenes where BVH rebuilds are a major bottleneck. Example: Flooded Sponza by Intel.

These pruned trees enable efficient evaluation of the SDF for rendering or discretization, resulting in >100x speedups for complex scenes compared to brute-force evaluation. Come to my talk next week for more details, or read the paper here: wbrbr.org/publications...

Weekend project: a simple SPH fluid simulator. It's clearly not very good yet, but it's starting to look like something! Fluids are fun
