Variable Bit Rate GPU Texture Decompression
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Variable bit rate compression can achieve better quality and compression rates than fixed bit rate methods. None the less, GPU texturing uses lossy fixed bit rate methods like DXT to allow random access and on-the-fly ... -
Vectorising Bitmaps into Semi-Transparent Gradient Layers
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an interactive approach for decompositing bitmap drawings and studio photographs into opaque and semi-transparent vector layers. Semi-transparent layers are especially challenging to extract, since they require ... -
Video Flashlights - Real Time Rendering of Multiple Videos for Immersive Model Visualization
(The Eurographics Association, 2002)Videos and 3D models have traditionally existed in separate worlds and as distinct representations. Although texture maps for 3D models have been traditionally derived from multiple still images, real-time mapping of live ... -
Visibility Editing For All-Frequency Shadow Design
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present an approach for editing shadows in all-frequency lighting environments. To support artistic control, we propose to decouple shadowing from lighting and focus on providing intuitive controls to edit the former. ... -
Visual Chatter in the Real World
(The Eurographics Association, 2006)When a scene is lit by a source of light, the radiance of each point in the scene can be viewed as having two components, namely, direct and global. Recently, an efFIcient separation method has been proposed that uses high ... -
Visualization of woven cloth
(The Eurographics Association, 2003)A technique for visualizing clothes is proposed that can handle rendering of complex weave patterns. An industrial standard of weave representation is used to derive the weave pattern and a detailed model of light interaction ... -
A Volumetric Approach to Predictive Rendering of Fabrics
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Efficient physically accurate modeling and rendering of woven cloth at a yarn level is an inherently complicated task due to the underlying geometrical and optical complexity. In this paper, a novel and general approach ... -
Warping and Partitioning for Low Error Shadow Maps
(The Eurographics Association, 2006)We evaluate several shadow map algorithms based on warping and partitioning using the maximum perspective aliasing error over the entire view frustum. With respect to our error metric, we show that a range of warping ... -
Wavelet Environment Matting
(The Eurographics Association, 2003)In this paper we present a novel approach for capturing the environment matte of a scene. We impose no restrictions on material properties of the objects in the captured scene and exploit scene characteristics (e.g. material ... -
Wavelet Point-Based Global Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Point-Based Global Illumination (PBGI) is a popular rendering method in special effects and motion picture productions. This algorithm provides a diffuse global illumination solution by caching radiance in a mesh-less ... -
Wavelet Radiance Transport for Interactive Indirect Lighting
(The Eurographics Association, 2006)Global illumination is a complex all-frequency phenomenon including subtle effects caused by indirect lighting. Computing global illumination interactively for dynamic lighting conditions has many potential applications, ... -
Whitted Ray-Tracing for Dynamic Scenes using a Ray-Space Hierarchy on the GPU
(The Eurographics Association, 2007)In this paper, we present a new algorithm for interactive rendering of animated scenes with Whitted Ray-Tracing, running on the GPU. We focus our attention on the secondary rays (the rays generated by one or more bounces ...
