Path Guiding Using Spatio‐Directional Mixture Models
(© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2022)
We propose a learning‐based method for light‐path construction in path tracing algorithms, which iteratively optimizes and samples from what we refer to as spatio‐directional Gaussian mixture models (SDMMs). In particular, ...
Learning Dynamic 3D Geometry and Texture for Video Face Swapping
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Face swapping is the process of applying a source actor's appearance to a target actor's performance in a video. This is a challenging visual effect that has seen increasing demand in film and television production. Recent ...
OutCast: Outdoor Single-image Relighting with Cast Shadows
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We propose a relighting method for outdoor images. Our method mainly focuses on predicting cast shadows in arbitrary novel lighting directions from a single image while also accounting for shading and global effects such ...
Meshlets and How to Shade Them: A Study on Texture-Space Shading
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Commonly used image-space layouts of shading points, such as used in deferred shading, are strictly view-dependent, which restricts efficient caching and temporal amortization. In contrast, texture-space layouts can represent ...
LOOPS: LOcally Optimized Polygon Simplification
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Displaying polygonal vector data is essential in various application scenarios such as geometry visualization, vector graphics rendering, CAD drawing and in particular geographic, or cartographic visualization. Dealing ...
Once-more Scattered Next Event Estimation for Volume Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We present a Monte Carlo path tracing technique to sample extended next event estimation contributions in participating media: we consider one additional scattering vertex on the way to the next event, accounting for focused ...
Progressive Denoising of Monte Carlo Rendered Images
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Image denoising based on deep learning has become a powerful tool to accelerate Monte Carlo rendering. Deep learning techniques can produce smooth images using a low sample count. Unfortunately, existing deep learning ...
Microsurface Transformations
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We derive a general result in microfacet theory: given an arbitrary microsurface defined via standard microfacet statistics, we show how to construct the statistics of its linearly transformed counterparts. A common use ...
Deterministic Linear Time for Maximal Poisson-Disk Sampling using Chocks without Rejection or Approximation
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We show how to sample uniformly within the three-sided region bounded by a circle, a radial ray, and a tangent, called a ''chock.'' By dividing a 2D planar rectangle into a background grid, and subtracting Poisson disks ...
MoCo-Flow: Neural Motion Consensus Flow for Dynamic Humans in Stationary Monocular Cameras
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Synthesizing novel views of dynamic humans from stationary monocular cameras is a specialized but desirable setup. This is particularly attractive as it does not require static scenes, controlled environments, or specialized ...
