Geometric Sample Reweighting for Monte Carlo Integration
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Numerical integration is fundamental in multiple Monte Carlo rendering problems. We present a sample reweighting scheme, including underlying theory, and analysis of numerical performance for the integration of an unknown ...
A Practical and Efficient Approach for Correct Z-Pass Stencil Shadow Volumes
(The Eurographics Association, 2019)
Shadow volumes are a popular technique to compute pixel-accurate hard shadows in 3D scenes. Many variants exist that trade off accuracy and efficiency. In this work, we present an artifact-free, efficient, and easy-to-implement ...
