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 ... -
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 ... -
Generation of Folded Terrains from Simple Vector Maps
(The Eurographics Association, 2015)While several terrain generation methods focused on plausible watersheds, the fact that most mountains should not be isolated but rather be part of wider scale mountain ranges was seldom considered. In this work, we present ... -
GHand: A GPU Algorithm for Realtime Hand Pose Estimation Using Depth Camera
(The Eurographics Association, 2015)We present GHand, a GPU algorithm for markerless hand pose estimation from a single depth image obtained from a commodity depth camera. Our method uses a dual random forest approach: the first forest estimates position and ... -
Guided Analysis of Cardiac 4D PC-MRI Blood Flow Data
(The Eurographics Association, 2015)Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI) allows the non-invasive acquisition of temporally resolved, three-dimensional blood flow information. Quantitative and qualitative data analysis helps ... -
Guiding Image Manipulations using Shape-appearance Subspaces from Co-alignment of Image Collections
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a system to restrict the manipulation of shape and appearance in an image to a valid subspace which we learn from a collection of exemplar images. To this end, we automatically co-align a collection of images ... -
Hallucinating Stereoscopy from a Single Image
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a novel method for enabling stereoscopic viewing of a scene from a single pre-segmented image. Rather than attempting full 3D reconstruction or accurate depth map recovery, we hallucinate a rough approximation ... -
Hardware-Based Non-Photorealistic Rendering Using a Painting Robot
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We describe a painting machine and associated algorithms. Our modified industrial robot works with visual feedback and applies acrylic paint from a repository to a canvas until the created painting resembles a given input ... -
High Reliefs from 3D Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a method for synthesizing high reliefs, a sculpting technique that attaches 3D objects onto a 2D surface within a limited depth range. The main challenges are the preservation of distinct scene parts by preserving ... -
High-Order Recursive Filtering of Non-Uniformly Sampled Signals for Image and Video Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a discrete-time mathematical formulation for applying recursive digital filters to non-uniformly sampled signals. Our solution presents several desirable features: it preserves the stability of the original ... -
High-Quality Shadows for Streaming Terrain Rendering
(The Eurographics Association, 2015)Rendering of large, detailed 3D terrains on commodity hardware has become possible through the use of raycasting, data caching and prefetching. Adding dynamic shadows as they appear during a day-night cycle remais a challenge ... -
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. ... -
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 ... -
Improving k-buffer Methods via Occupancy Maps
(The Eurographics Association, 2015)In this work, we investigate an efficient approach to treat fragment racing when computing k-nearest fragments. Based on the observation that knowing the depth position of the k-th fragment we can optimally find the k-closest ... -
Improving Sampling-based Motion Control
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We address several limitations of the sampling-based motion control method of Liu et at. [LYvdP 10]. The key insight is to learn from the past control reconstruction trials through sample distribution adaptation. Coupled ... -
Individual Time Stepping for SPH Fluids
(The Eurographics Association, 2015)We present a novel adaptive stepping scheme for SPH fluids, in which particles have their own time-steps determined from local conditions, e.g. Courant condition. These individual time-steps are constrained for global ... -
InfoView3D: A Solution Showing Educational Model on Multi-Touch Surfaces
(The Eurographics Association, 2015)In this paper, we present a solution for educational presentation which can integrate images, documents, videos, and especially 3D models in a tree based structure. The solution is based on HTML5 and JavaScript, using SVG ... -
Interactive Dimensioning of Parametric Models
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a solution for the dimensioning of parametric and procedural models. Dimensioning has long been a staple of technical drawings, and we present the first solution for interactive dimensioning: a dimension line ... -
Interactive Disassembly Planning for Complex Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an approach for the automatic generation, interactive exploration and real-time modification of disassembly procedures for complex, multipartite CAD data sets. In order to lift the performance barriers prohibiting ... -
An Interactive Editing System for Visual Appearances of Fire and Explosions
(The Eurographics Association, 2015)Synthetic volumetric fire and explosions are important visual effects used in many applications such as computer games and movies. For these applications, artists are often requested to achieve the desired visual appearance ...
