Gradient-Domain Path Reusing

Summary: We present gradient-domain path reusing, a novel unbiased Monte-Carlo rendering technique, which merges the concept of path reusing with gradient-domain rendering. It outperforms conventional and gradient-domain path, and traditional path reusing tracing by up to almost an order of magnitude.

Real-time Global Illumination by Precomputed Local Reconstruction from Sparse Radiance Probes

Summary: We present a direct-to-indirect transport technique that enables accurate real- time rendering of indirect illumination in mostly static scenes of complexity on par with modern games while supporting fully dynamic lights, cameras and diffuse surface materials.

Fast Rendering of Fabric Micro-Appearance Models Under Directional and Spherical Gaussian Lights

Summary: We present a fast, precomputation-based algorithm for rendering both single and multiple scattering in fabrics with repeating structure illuminated by directional and spherical Gaussian lights. We show how to decompose the problem and pick the right approximations to achieve very high accuracy, with significant performance gains over path tracing

Weighted Linde-Buzo-Gray Stippling

Summary: We propose an adaptive version of Lloyd's optimization method that distributes points based on Voronoi Diagrams. Our inspiration comes from the Linde-Buzo-Gray-Algorithm in Vector quantization, which dynamically splits and merges Voronoi cells until a given goal is reached.
