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). ... -
Diffuse-Specular Separation using Binary Spherical Gradient Illumination
(The Eurographics Association, 2018)We introduce a novel method for view-independent diffuse-specular separation of albedo and photometric normals without requiring polarization using binary spherical gradient illumination. The key idea is that with binary ... -
PN-Method for Multiple Scattering in Participating Media
(The Eurographics Association, 2018)Rendering highly scattering participating media using brute force path tracing is a challenge. The diffusion approximation reduces the problem to solving a simple linear partial differential equation. Flux-limited diffusion ... -
Scalable Real-Time Shadows using Clustering and Metric Trees
(The Eurographics Association, 2018)Real-time shadow algorithms based on geometry generally produce high quality shadows. Recent works have considerably improved their efficiency. However, scalability remains an issue because these methods strongly depend ... -
A Unified Manifold Framework for Efficient BRDF Sampling based on Parametric Mixture Models
(The Eurographics Association, 2018)Virtually all existing analytic BRDF models are built from multiple functional components (e.g., Fresnel term, normal distribution function, etc.). This makes accurate importance sampling of the full model challenging, and ... -
Deep Hybrid Real and Synthetic Training for Intrinsic Decomposition
(The Eurographics Association, 2018)Intrinsic image decomposition is the process of separating the reflectance and shading layers of an image, which is a challenging and underdetermined problem. In this paper, we propose to systematically address this problem ... -
Matrix Bidirectional Path Tracing
(The Eurographics Association, 2018)Sampled paths in Monte Carlo ray tracing can be arbitrarily close to each other due to its stochastic nature. Such clumped samples in the path space tend to contribute little toward an accurate estimate of each pixel. ... -

Approximate svBRDF Estimation From Mobile Phone Video
(The Eurographics Association, 2018)We describe a new technique for obtaining a spatially varying BRDF (svBRDF) of a flat object using printed fiducial markers and a cell phone capable of continuous flash video. Our homography-based video frame alignment ... -
Primary Sample Space Path Guiding
(The Eurographics Association, 2018)Guiding path tracing in light transport simulation has been one of the practical choices for variance reduction in production rendering. For this purpose, typically structures in the spatial-directional domain are built. ... -
Soft Transparency for Point Cloud Rendering
(The Eurographics Association, 2018)We propose a novel rendering framework for visualizing point data with complex structures and/or different quality of data. The point cloud can be characterized by setting a per-point scalar field associated to the aspect ... -
Screen Space Approximate Gaussian Hulls
(The Eurographics Association, 2018)The Screen Space Approximate Gaussian Hull method presented in this paper is based on an output sensitive, adaptive approach, which addresses the challenge of high quality rendering even for high resolution displays and ...
