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 ... -
Levitating Rigid Objects with Hidden Rods and Wires
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We propose a novel algorithm to efficiently generate hidden structures to support arrangements of floating rigid objects. Our optimization finds a small set of rods and wires between objects and each other or a supporting ... -
LoBSTr: Real-time Lower-body Pose Prediction from Sparse Upper-body Tracking Signals
(The Eurographics Association and John Wiley & Sons Ltd., 2021)With the popularization of games and VR/AR devices, there is a growing need for capturing human motion with a sparse set of tracking data. In this paper, we introduce a deep neural network (DNN) based method for real-time ... -
Local Light Alignment for Multi-Scale Shape Depiction
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Motivated by recent findings in the field of visual perception, we present a novel approach for enhancing shape depiction and perception of surface details. We propose a shading-based technique that relies on locally ... -
MultiResGNet: Approximating Nonlinear Deformation via Multi-Resolution Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2021)This paper presents a graph-learning-based, powerfully generalized method for automatically generating nonlinear deformation for characters with an arbitrary number of vertices. Large-scale character datasets with a ... -
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 ... -
Neural Acceleration of Scattering-Aware Color 3D Printing
(The Eurographics Association and John Wiley & Sons Ltd., 2021)With the wider availability of full-color 3D printers, color-accurate 3D-print preparation has received increased attention. A key challenge lies in the inherent translucency of commonly used print materials that blurs out ... -
Orthogonalized Fourier Polynomials for Signal Approximation and Transfer
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We propose a novel approach for the approximation and transfer of signals across 3D shapes. The proposed solution is based on taking pointwise polynomials of the Fourier-like Laplacian eigenbasis, which provides a compact ... -
Patch Erosion for Deformable Lapped Textures on 3D Fluids
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We propose an approach to synthesise a texture on an animated fluid free surface using a distortion metric combined with a feature map. Our approach is applied as a post-process to a fluid simulation. We advect deformable ... -
Perceptual Quality of BRDF Approximations: Dataset and Metrics
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Bidirectional Reflectance Distribution Functions (BRDFs) are pivotal to the perceived realism in image synthesis. While measured BRDF datasets are available, reflectance functions are most of the time approximated by ... -
Physically-based Book Simulation with Freeform Developable Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Reading books or articles digitally has become accessible and widespread thanks to the large amount of affordable mobile devices and distribution platforms. However, little effort has been devoted to improving the digital ... -
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 ... -
Quad Layouts via Constrained T-Mesh Quantization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a robust and fast method for the creation of conforming quad layouts on surfaces. Our algorithm is based on the quantization of a T-mesh, i.e. an assignment of integer lengths to the sides of a non-conforming ... -
Rank-1 Lattices for Efficient Path Integral Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We introduce rank-1 lattices as a quasi-random sequence to the numerical estimation of the high-dimensional path integral. Previous attempts at utilizing rank-1 lattices in computer graphics were very limited to low-dimensional ... -
Real-Time Frequency Adjustment of Images and Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a technique for real-time adjustment of spatial frequencies in images and videos. Our method allows for both decreasing and increasing of frequencies, and is orthogonal to image resizing. Thus, it can be used ... -
