Neural Sequence Transformation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Monte Carlo integration is a technique for numerically estimating a definite integral by stochastically sampling its integrand. These samples can be averaged to make an improved estimate, and the progressive estimates form ...
Consistent Post-Reconstruction for Progressive Photon Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Photon mapping is a light transport algorithm that simulates various rendering effects (e.g., caustics) robustly, and its progressive variants, progressive photon mapping (PPM) methods, can produce a biased but consistent ...
A Multi-pass Method for Accelerated Spectral Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Spectral Monte Carlo rendering can simulate advanced light phenomena, such as chromatic dispersion, but typically shows a slow convergence behavior. Properly sampling the spectral domain can be challenging in scenes with ...
Real-time Denoising Using BRDF Pre-integration Factorization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Path tracing has been used for real-time renderings, thanks to the powerful GPU device. Unfortunately, path tracing produces noisy rendered results, thus, filtering or denoising is often applied as a post-process to remove ...
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 ...
