The Gödel Engine - An Interactive Approach to Visualization in General Relativity
(The Eurographics Association and Blackwell Publishing Ltd., 2009)
We present a methodical new approach to visualize the aspects of general relativity from a self-centered perspective. We focus on the visualization of the Gödel universe, which is an exact solution to Einstein s field ...
Path Guiding with Vertex Triplet Distributions
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Good importance sampling strategies are decisive for the quality and robustness of photorealistic image synthesis with Monte Carlo integration. Path guiding approaches use transport paths sampled by an existing base sampler ...
Markov Chain Mixture Models for Real-Time Direct Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2023)
We present a novel technique to efficiently render complex direct illumination in real-time. It is based on a spatio-temporal randomized mixture model of von Mises-Fisher (vMF) distributions in screen space. For every pixel ...
