An Improved Multiple Importance Sampling Heuristic for Density Estimates in Light Transport Simulations
(The Eurographics Association, 2018)
Vertex connection and merging (VCM) is one of the most robust light transport simulation algorithms developed so far. It combines bidirectional path tracing with photon mapping using multiple importance sampling (MIS). ...
Pixel Cache Light Tracing
(The Eurographics Association, 2017)
In this paper, we introduce Pixel Cache Light Tracing, which is a new low-noise combination of eye-path and light-path tracing. In the first pass, eye-path vertices are distributed from the observer and stored in a hit ...
Multi-Layer Alpha Tracing
(The Eurographics Association, 2020)
Rendering many transparent surfaces in real-time is still an open problem. We introduce two techniques for fast transparency rendering with ray tracing hardware, one being exact and the other being approximate but of high ...
Interactive Visualization of Gaps and Overlaps for Large and Dynamic Sphere Packings
(The Eurographics Association, 2017)
To gain insight into many properties of granular matter, a particle packing can be simulated. For a dry particle mixture, collective rearrangement is often used as an iterative process to place the particles. In this paper, ...
Relaxed Parallel Priority Queue with Filter Levels for Parallel Mesh Decimation
(The Eurographics Association, 2022)
We propose a novel implementation of a parallel priority queue in the context of multithreaded mesh decimation. Previous parallel priority queues either have a major bottleneck when extracting nodes, cannot guarantee ...
Stenciled Volumetric Ambient Occlusion
(The Eurographics Association, 2022)
Screen-space Ambient Occlusion (AO) is commonly used in games to calculate the exposure of each pixel to ambient lighting with the help of a depth buffer. Due to its screen-space nature, it suffers from several artifacts ...
