Z-Thickness Blending: Effective Fragment Merging for Multi-Fragment Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
An effective fragment merging technique is presented in this study that addresses multi-fragment problems, including fragment overflow and z-fighting, and provides visual effects that are beneficial for various screen-space ...
SnakeBinning: Efficient Temporally Coherent Triangle Packing for Shading Streaming
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Streaming rendering, e.g., rendering in the cloud and streaming via a mobile connection, suffers from increased latency and unreliable connections. High quality framerate upsampling can hide these issues, especially when ...
Temporally Reliable Motion Vectors for Real-time Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Real-time ray tracing (RTRT) is being pervasively applied. The key to RTRT is a reliable denoising scheme that reconstructs clean images from significantly undersampled noisy inputs, usually at 1 sample per pixel as limited ...
ReSTIR GI: Path Resampling for Real-Time Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Even with the advent of hardware-accelerated ray tracing in modern GPUs, only a small number of rays can be traced at each pixel in real-time applications. This presents a significant challenge for path tracing, even when ...
Correlation-Aware Multiple Importance Sampling for Bidirectional Rendering Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Combining diverse sampling techniques via multiple importance sampling (MIS) is key to achieving robustness in modern Monte Carlo light transport simulation. Many such methods additionally employ correlated path sampling ...
Cyclostationary Gaussian Noise: Theory and Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Stationary Gaussian processes have been used for decades in the context of procedural noises to model and synthesize textures with no spatial organization. In this paper we investigate cyclostationary Gaussian processes, ...
A Multiscale Microfacet Model Based on Inverse Bin Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Accurately controllable shading detail is a crucial aspect of realistic appearance modelling. Two fundamental building blocks for this are microfacet BRDFs, which describe the statistical behaviour of infinitely small ...
Optimised Path Space Regularisation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We present Optimised Path Space Regularisation (OPSR), a novel regularisation technique for forward path tracing algorithms. Our regularisation controls the amount of roughness added to materials depending on the type of ...
Thin-Volume Visualization on Curved Domains
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Thin, curved structures occur in many volumetric datasets. Their analysis using classical volume rendering is difficult because parts of such structures can bend away or hide behind occluding elements. This problem cannot ...
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 ...
