A Multilevel SPH Solver with Unified Solid Boundary Handling
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We propose a geometric multilevel solver for efficiently solving linear systems arising from particle-based methods. To apply this method to particle systems, we construct the hierarchy, establish the correspondence between ... -
Harmonic Functions for Rotational Symmetry Vector Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Representing rotational symmetry vector as a set of vectors is not suitable for design due to lacking of a consistent ordering for measurement. In this paper we introduce a spectral method to find rotation invariant harmonic ... -
Visual Contrast Sensitivity and Discrimination for 3D Meshes and their Applications
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In this paper, we first introduce an algorithm for estimating the visual contrast on a 3D mesh. We then perform a series of psychophysical experiments to study the effects of contrast sensitivity and contrast discrimination ... -
Tracing Field-Coherent Quad Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Given a cross field over a triangulated surface we present a practical and robust method to compute a field aligned coarse quad layout over the surface. The method works directly on a triangle mesh without requiring any ... -
Progressive Compression of Arbitrary Textured Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In this paper, we present a progressive compression algorithm for textured surface meshes, which is able to handle polygonal non-manifold meshes as well as discontinuities in the texture mapping. Our method applies iterative ... -
Reduced Aggregate Scattering Operators for Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Aggregate scattering operators (ASOs) describe the overall scattering behavior of an asset (i.e., an object or volume, or collection thereof) accounting for all orders of its internal scattering. We propose a practical way ... -
Variance Analysis of Multi-sample and One-sample Multiple Importance Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We reexamine in this paper the variance for the Multiple Importance Sampling (MIS) estimator for multi-sample and onesample model. As a result of our analysis we can obtain the optimal estimator for the multi-sample model ... -
Decoupled Space and Time Sampling of Motion and Defocus Blur for Unified Rendering of Transparent and Opaque Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We propose a unified rendering approach that jointly handles motion and defocus blur for transparent and opaque objects at interactive frame rates. Our key idea is to create a sampled representation of all parts of the ... -
An Error Estimation Framework for Many-Light Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2016)The popularity of many-light rendering, which converts complex global illumination computations into a simple sum of the illumination from virtual point lights (VPLs), for predictive rendering has increased in recent years. ... -
Physically Based Video Editing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Convincing manipulation of objects in live action videos is a difficult and often tedious task. Skilled video editors achieve this with the help of modern professional tools, but complex motions might still lack physical ... -
Feature-Aware Pixel Art Animation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Pixel art is a modern digital art in which high resolution images are abstracted into low resolution pixelated outputs using concise outlines and reduced color palettes. Creating pixel art is a labor intensive and ... -
Efficient Multi-image Correspondences for On-line Light Field Video Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Light field videos express the entire visual information of an animated scene, but their shear size typically makes capture, processing and display an off-line process, i. e., time between initial capture and final display ... -
Facial Feature Exaggeration According to Social Psychology of Face Perception
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We propose a personality trait exaggeration system emphasizing the impression of human face in images, based on multi-level features learning and exaggeration. These features are called Personality Trait Model(PTM). Abstract ... -
Merged Multiresolution Hierarchies for Shadow Map Compression
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Multiresolution Hierarchies (MH) and Directed Acyclic Graphs (DAG) are two recent approaches for the compression of highresolution shadow information. In this paper, we introduce Merged Multiresolution Hierarchies (MMH), ... -
Multiple Scattering Approximation in Heterogeneous Media by Narrow Beam Distributions
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Fast realistic rendering of objects in scattering media is still a challenging topic in computer graphics. In presence of participating media, a light beam is repeatedly scattered by media particles, changing direction and ... -
Pixel History Linear Models for Real-Time Temporal Filtering
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We propose a new real-time temporal filtering and antialiasing (AA) method for rasterization graphics pipelines. Our method is based on Pixel History Linear Models (PHLM), a new concept for modeling the history of pixel ... -
Proxy-guided Image-based Rendering for Mobile Devices
(The Eurographics Association and John Wiley & Sons Ltd., 2016)VR headsets and hand-held devices are not powerful enough to render complex scenes in real-time. A server can take on the rendering task, but network latency prohibits a good user experience. We present a new image-based ... -
Anaglyph Caustics with Motion Parallax
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In this paper we present a method to model and simulate a lens such that its caustic reveals a stereoscopic 3D image when viewed through anaglyph glasses. By interpreting lens dispersion as stereoscopic disparity, our ... -
Direct Shape Optimization for Strengthening 3D Printable Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Recently there has been an increasing demand for software that can help designers create functional 3D objects with required physical strength. We introduce a generic and extensible method that directly optimizes a shape ... -
An Interactive Design System of Free-Formed Bamboo-Copters
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present an interactive design system for designing free-formed bamboo-copters, where novices can easily design freeformed, even asymmetric bamboo-copters that successfully fly. The designed bamboo-copters can be fabricated ...
