Spherical Voronoi Unveiled: Real-Time Photorealism Without Neural Giants

We dive into Spherical Voronoi (SV), a new framework that partitions viewing directions on the sphere with adaptive Voronoi cells to capture sharp reflections and high-frequency lighting in real-time rendering. See how SV uses a single softmax temperature to smoothly span diffuse to mirror-like highlights, outperforming traditional approaches like spherical harmonics and even neural baselines such as ZipNerf, all with an explicit, stable model. We'll discuss Voronoi light probes, benchmark results, and what this means for achieving real-time photorealism in games and VR.
