Alpha Compression with Variable Data Formats
(The Eurographics Association, 2011)
Based on the insight into the essential differences between transparency and color, we present a novel alpha compression scheme, called EAC (Enhanced Alpha Compression), as an improvement to that of DXT5. EAC defines new ...
Fast Hydraulic and Thermal Erosion on GPU
(The Eurographics Association, 2011)
Computer games, simulators and many other computer graphics applications display external scenes where a realistic looking terrain is a vital part of the view. In this paper we propose a method that generates realistic ...
Enhancing Image-Based Aging Approaches
(The Eurographics Association, 2011)
Modern video games and computer-animated movies exhibit extremely realistic synthetic images. To achieve such a level of realism, artists have to consider several characteristics including material appearance changes from ...
An Error Bound for Decoupled Visibility with Application to Relighting
(The Eurographics Association, 2011)
Monte Carlo estimation of direct lighting is often dominated by visibility queries. If an error is tolerable, the calculations can be sped up by using a simple scalar occlusion factor per light source to attenuate radiance, ...
Skimming Video Action Using Annotated 3D Surfaces
(The Eurographics Association, 2011)
It has become all too clear that despite the ever-growing reams of available media, we face diminishing strategic returns from it unless we craft better tools that not only let us playback media but also get us quickly to ...
Volumetric plastic deformation
(The Eurographics Association, 2011)
Working with volumetric information is always challenging. Displaying, processing or modifying volumes requires in most cases processing a considerable part of them, if not the whole structure. Such delays might be ...
Improving Shadow Map Filtering with Statistical Analysis
(The Eurographics Association, 2011)
Shadow maps are widely used in real-time applications. Shadow maps cannot be filtered linearly as regular textures, thus undersampling leads to severe aliasing. This problem has been attacked by methods that transform the ...
Folded Paper Geometry from 2D Pattern and 3D Contour
(The Eurographics Association, 2011)
Folded paper exhibits very characteristic shapes, due to the presence of sharp folds and to exact isometry with a given planar pattern. Therefore, none of the physically-based simulators developed so far can handle paper-like ...
Realistic Simulation of Peripheral Vision Using An Aspherical Eye Model
(The Eurographics Association, 2011)
A novel method is proposed to accurately simulate the peripheral vision under different visual perception. An accurate aspherical schematic eye model is firstly introduced to reasonably predict the anatomical and optical ...
Warp-based Motion Compensation for Endoscopic Kymography
(The Eurographics Association, 2011)
Endoscopic videokymography is a method for visualizing the motion of the plica vocalis (vocal folds) for medical diagnosis. The diagnostic interpretability of a kymogram deteriorates if camera motion interferes with vocal ...
