Optimal Spline Approximation via l0-Minimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Splines are part of the standard toolbox for the approximation of functions and curves in Rd. Still, the problem of finding the spline that best approximates an input function or curve is ill-posed, since in general this ... -
Statics Aware Grid Shells
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a framework for the generation of polygonal grid-shell architectural structures, whose topology is designed in order to excel in static performances. We start from the analysis of stress on the input surface ... -
General and Robust Error Estimation and Reconstruction for Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Adaptive filtering techniques have proven successful in handling non-uniform noise in Monte-Carlo rendering approaches. A recent trend is to choose an optimal filter per pixel from a selection of non spatially-varying ... -
Selective Degree Elevation for Multi-Sided Bézier Patches
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper presents a method to selectively elevate the degree of an S-Patch of arbitrary dimension. We consider not only S-Patches with 2D domains but 3D and higher-dimensional domains as well, of which volumetric cage ... -
Robust Statistical Pixel Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Robust statistical methods are employed to reduce the noise in Monte Carlo ray tracing. Through the use of resampling, the sample mean distribution is determined for each pixel. Because this distribution is uni-modal and ... -
Rich-VPLs for Improving the Versatility of Many-Light Methods
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many-light methods approximate the light transport in a scene by computing the direct illumination from many virtual point light sources (VPLs), and render low-noise images covering a wide range of performance and quality ... -
IlluminationCut
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel algorithm, IlluminationCut, for rendering images using the many-lights framework. It handles any light source that can be approximated with virtual point lights (VPLs) as well as highly glossy materials. ... -
Partitioned Shadow Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Real-time shadows remain a challenging problem in computer graphics. In this context, shadow algorithms generally rely either on shadow mapping or shadow volumes. This paper rediscovers an old class of algorithms that build ... -
CHC+RT: Coherent Hierarchical Culling for Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a new technique for in-core and out-of-core GPU ray tracing using a generalization of hierarchical occlusion culling in the style of the CHC++ method. Our method exploits the rasterization pipeline and hardware ... -
T-SAH: Animation Optimized Bounding Volume Hierarchies
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a method for creating a bounding volume hierarchy (BVH) that is optimized for all frames of a given animated scene. The method is based on a novel extension of surface area heuristic to temporal domain (T-SAH). ... -
Generating Design Suggestions under Tight Constraints with Gradient-based Probabilistic Programming
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a system for generating suggestions from highly-constrained, continuous design spaces. We formulate suggestion as sampling from a probability distribution; constraints are represented as factors that concentrate ... -
Replaceable Substructures for Efficient Part-Based Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)A popular mode of shape synthesis involves mixing and matching parts from different objects to form a coherent whole. The key challenge is to efficiently synthesize shape variations that are plausible, both locally and ... -
Implicit Formulation for SPH-based Viscous Fluids
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a stable and efficient particle-based method for simulating highly viscous fluids that can generate coiling and buckling phenomena and handle variable viscosity. In contrast to previous methods that use explicit ... -
A Cut-Cell Geometric Multigrid Poisson Solver for Fluid Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel multigrid scheme based on a cut-cell formulation on regular staggered grids which generates compatible systems of linear equations on all levels of the multigrid hierarchy. This geometrically motivated ... -
A Dimension-reduced Pressure Solver for Liquid Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This work presents a method for efficiently simplifying the pressure projection step in a liquid simulation. We first devise a straightforward dimension reduction technique that dramatically reduces the cost of solving the ... -
Adaptable Anatomical Models for Realistic Bone Motion Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a system to reconstruct subject-specific anatomy models while relying only on exterior measurements represented by point clouds. Our model combines geometry, kinematics, and skin deformations (skinning). This ... -
SmartAnnotator: An Interactive Tool for Annotating Indoor RGBD Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)RGBD images with high quality annotations, both in the form of geometric (i.e., segmentation) and structural (i.e., how do the segments mutually relate in 3D) information, provide valuable priors for a diverse range of ... -
Database-Assisted Object Retrieval for Real-Time 3D Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In recent years, real-time 3D scanning technology has developed significantly and is now able to capture large environments with considerable accuracy. Unfortunately, the reconstructed geometry still suffers from incompleteness, ... -
Biologically-Inspired Visual Simulation of Insect Swarms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Representing the majority of living animals, insects are the most ubiquitous biological organisms on Earth. Being able to simulate insect swarms could enhance visual realism of various graphical applications. However, the ...
