Learning Multiple-Scattering Solutions for Sphere-Tracing of Volumetric Subsurface Effects
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Accurate subsurface scattering solutions require the integration of optical material properties along many complicated light paths. We present a method that learns a simple geometric approximation of random paths in a ...
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 ...
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 ...
Practical Face Reconstruction via Differentiable Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We present a differentiable ray-tracing based novel face reconstruction approach where scene attributes - 3D geometry, reflectance (diffuse, specular and roughness), pose, camera parameters, and scene illumination - are ...
