HalfedgeCNN for Native and Flexible Deep Learning on Triangle Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We describe HalfedgeCNN, a collection of modules to build neural networks that operate on triangle meshes. Taking inspiration from the (edge-based) MeshCNN, convolution, pooling, and unpooling layers are consistently defined ... -
Accelerating Hair Rendering by Learning High-Order Scattered Radiance
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Efficiently and accurately rendering hair accounting for multiple scattering is a challenging open problem. Path tracing in hair takes long to converge while other techniques are either too approximate while still being ... -
A Practical and Hierarchical Yarn-based Shading Model for Cloth
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Realistic cloth rendering is a longstanding challenge in computer graphics due to the intricate geometry and hierarchical structure of cloth: Fibers form plies which in turn are combined into yarns which then are woven or ... -
Iridescent Water Droplets Beyond Mie Scattering
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Looking at a cup of hot tea, an observer can see color patterns and granular textures both on the water surface and in the steam. Motivated by this example, we model the appearance of iridescent water droplets. Mie scattering ... -
LoCoPalettes: Local Control for Palette-based Image Editing
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Palette-based image editing takes advantage of the fact that color palettes are intuitive abstractions of images. They allow users to make global edits to an image by adjusting a small set of colors. Many algorithms have ... -
Interactive Control over Temporal Consistency while Stylizing Video Streams
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Image stylization has seen significant advancement and widespread interest over the years, leading to the development of a multitude of techniques. Extending these stylization techniques, such as Neural Style Transfer ... -
PVP: Personalized Video Prior for Editable Dynamic Portraits using StyleGAN
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Portrait synthesis creates realistic digital avatars which enable users to interact with others in a compelling way. Recent advances in StyleGAN and its extensions have shown promising results in synthesizing photorealistic ... -
Practical Acquisition of Shape and Plausible Appearance of Reflective and Translucent Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present a practical method for acquisition of shape and plausible appearance of reflective and translucent objects for realistic rendering and relighting applications. Such objects are extremely challenging to scan with ... -
ModalNeRF: Neural Modal Analysis and Synthesis for Free-Viewpoint Navigation in Dynamically Vibrating Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Recent advances in Neural Radiance Fields enable the capture of scenes with motion. However, editing the motion is hard; no existing method allows editing beyond the space of motion existing in the original video, nor ... -
A Hyperspectral Space of Skin Tones for Inverse Rendering of Biophysical Skin Properties
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present a method for estimating the main properties of human skin, leveraging a hyperspectral dataset of skin tones synthetically generated through a biophysical layered skin model and Monte Carlo light transport ... -
One-to-Many Spectral Upsampling of Reflectances and Transmittances
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Spectral rendering is essential for the production of physically-plausible synthetic images, but requires to introduce several changes in the content generation pipeline. In particular, the authoring of spectral material ... -
Neural Free-Viewpoint Relighting for Glossy Indirect Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Precomputed Radiance Transfer (PRT) remains an attractive solution for real-time rendering of complex light transport effects such as glossy global illumination. After precomputation, we can relight the scene with new ... -
Efficient Path-Space Differentiable Volume Rendering With Respect To Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Differentiable rendering of translucent objects with respect to their shapes has been a long-standing problem. State-of-theart methods require detecting object silhouettes or specifying change rates inside translucent ... -
Ray-aligned Occupancy Map Array for Fast Approximate Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present a new software ray tracing solution that efficiently computes visibilities in dynamic scenes. We first introduce a novel scene representation: ray-aligned occupancy map array (ROMA) that is generated by rasterizing ... -
NEnv: Neural Environment Maps for Global Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Environment maps are commonly used to represent and compute far-field illumination in virtual scenes. However, they are expensive to evaluate and sample from, limiting their applicability to real-time rendering. Previous ... -
Markov Chain Mixture Models for Real-Time Direct Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present a novel technique to efficiently render complex direct illumination in real-time. It is based on a spatio-temporal randomized mixture model of von Mises-Fisher (vMF) distributions in screen space. For every pixel ... -
