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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
