Adversarial Single-Image SVBRDF Estimation with Hybrid Training
(The Eurographics Association and John Wiley & Sons Ltd., 2021)In this paper, we propose a deep learning approach for estimating the spatially-varying BRDFs (SVBRDF) from a single image. Most existing deep learning techniques use pixel-wise loss functions which limits the flexibility ... -
Automatic Surface Segmentation for Seamless Fabrication Using 4-axis Milling Machines
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We introduce a novel geometry-processing pipeline to guide the fabrication of complex shapes from a single block of material using 4-axis CNC milling machines. This setup extends classical 3-axis CNC machining with an extra ... -
Coherent Mark-based Stylization of 3D Scenes at the Compositing Stage
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a novel temporally coherent stylized rendering technique working entirely at the compositing stage. We first generate a distribution of 3D anchor points using an implicit grid based on the local object positions ... -
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, ... -
Enabling Viewpoint Learning through Dynamic Label Generation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Optimal viewpoint prediction is an essential task in many computer graphics applications. Unfortunately, common viewpoint qualities suffer from two major drawbacks: dependency on clean surface meshes, which are not always ... -
Hierarchical Raster Occlusion Culling
(The Eurographics Association and John Wiley & Sons Ltd., 2021)This paper presents a scalable online occlusion culling algorithm, which significantly improves the previous raster occlusion culling using object-level bounding volume hierarchy. Given occluders found with temporal ... -
Higher Dimensional Graphics: Conceiving Worlds in Four Spatial Dimensions and Beyond
(The Eurographics Association and John Wiley & Sons Ltd., 2021)While the interpretation of high-dimensional datasets has become a necessity in most industries, the spatial visualization of higher-dimensional geometry has mostly remained a niche research topic for mathematicians and ... -
Honey, I Shrunk the Domain: Frequency-aware Force Field Reduction for Efficient Fluids Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Fluid control often uses optimization of control forces that are added to a simulation at each time step, such that the final animation matches a single or multiple target density keyframes provided by an artist. The ... -
Interactive Photo Editing on Smartphones via Intrinsic Decomposition
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Intrinsic decomposition refers to the problem of estimating scene characteristics, such as albedo and shading, when one view or multiple views of a scene are provided. The inverse problem setting, where multiple unknowns ... -
Layout Embedding via Combinatorial Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We consider the problem of injectively embedding a given graph connectivity (a layout) into a target surface. Starting from prescribed positions of layout vertices, the task is to embed all layout edges as intersection-free ... -
Learning and Exploring Motor Skills with Spacetime Bounds
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Equipping characters with diverse motor skills is the current bottleneck of physics-based character animation. We propose a Deep Reinforcement Learning (DRL) framework that enables physics-based characters to learn and ... -
Learning Human Search Behavior from Egocentric Visual Inputs
(The Eurographics Association and John Wiley & Sons Ltd., 2021)''Looking for things'' is a mundane but critical task we repeatedly carry on in our daily life. We introduce a method to develop a human character capable of searching for a randomly located target object in a detailed 3D ... -
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 ... -
