|Overview:||Advances in Real-Time Voxel-Based GI (Alexey Panteleev, NVIDIA) (Rahul Sathe, NVIDIA)Voxel based lighting has been around for a few years, but very few games have actually used it so far. In this session, we're going to discuss VXGI, the Nvidia's voxel based lighting solution, and uncover some recent improvements that aim to make it more practical and useful even for VR games on present day graphics hardware. We will also discuss how simple, planar area lights can be efficiently implemented with a combination of voxel-based occlusion and analytic irradiance calculations.Temporal Super-Resolution (Marco Salvi, NVIDIA)Marco Salvi will present a simple, but powerful extension to temporal anti-aliasing that combine anti-aliasing and super-resolution. The resulting algorithm, TSRAA, adds only a small runtime cost, is easier to integrate into a rendering engine than complex schemes like checkerboarding, and allows for flexible amounts of super-resolution.|
