Effective Compression Techniques for Precomputed Visibility
(The Eurographics Association, 1999)In rendering large models, it is important to identify the small subset of primitives that is visible from a given viewpoint. One approach is to partition the viewpoint space into viewpoint cells, and then precompute a ... -
Efficient and Accurate Rendering of Complex Light Sources
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a new method for estimating the radiance function of complex area light sources. The method is based on Jensen s photon mapping algorithm. In order to capture high angular frequencies in the radiance function, ... -
Efficient and Realistic Visualization of Cloth
(The Eurographics Association, 2003)Efficient and realistic rendering of cloth is of great interest especially in the context of e-commerce. Aside from the simulation of cloth draping, the rendering has to provide the "look and feel" of the fabric itself. ... -
Efficient Basis Decomposition for Scattered Reflectance Data
(The Eurographics Association, 2007)Recent progress in acquisition technology has increased the availability and quality of measured appearance data. Although representations based on dimensionality reduction provide the greatest fidelity to measured data, ... -
Efficient Cloth Modeling and Rendering
(The Eurographics Association, 2001)Realistic modeling and high-performance rendering of cloth and clothing is a challenging problem. Often these materials are seen at distances where individual stitches and knits can be made out and need to be accounted ... -
Efficient Computation of Blue Noise Point Sets through Importance Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Dart-throwing can generate ideal Poisson-disk distributions with excellent blue noise properties, but is very computationally expensive if a maximal point set is desired. In this paper, we observe that the Poisson-disk ... -
Efficient Displacement Mapping by Image Warping
(The Eurographics Association, 1999)While displacement maps can provide a rich set of visual detail on otherwise simple surfaces, they have always been very expensive to render. Rendering has been done using ray-tracing and by introducing a great number of ... -
Efficient High Quality Rendering of Point Sampled Geometry
(The Eurographics Association, 2002)We propose a highly efficient hierarchical representation for point sampled geometry that automatically balances sampling density and point coordinate quantization. The representation is very compact with a memory consumption ... -
An Efficient Hybrid Shadow Rendering Algorithm
(The Eurographics Association, 2004)We present a hybrid algorithm for rendering hard shadows accurately and efficiently. Our method combines the strengths of shadow maps and shadow volumes. We first use a shadow map to identify the pixels in the image that ... -
Efficient Illumination by High Dynamic Range Images
(The Eurographics Association, 2003)We present an algorithm for determining quadrature rules for computing the direct illumination of predominantly diffuse objects by high dynamic range images. The new method precisely reproduces fine shadow detail, is much ... -
Efficient Isotropic BRDF Measurement
(The Eurographics Association, 2003)In this paper we present novel reflectance measurement procedures that require fewer total measurements than standard uniform sampling approaches. First, we acquire densely sampled reflectance data for a large collection ... -
An Efficient Multi-View Rasterization Architecture
(The Eurographics Association, 2006)TV have been designed and built. However, these displays have received relatively little attention in the context of real-time computer graphics. We present a novel rasterization architecture that rasterizes each triangle ... -
Efficient Packing of Arbitrarily Shaped Charts for Automatic Texture Atlas Generation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Texture atlases are commonly used as representations for mesh parameterizations in numerous applications including texture and normal mapping. Therefore, packing is an important post-processing step that tries to place and ... -
Efficient Rendering of Atmospheric Phenomena
(The Eurographics Association, 2004)Rendering of atmospheric bodies involves modeling the complex interaction of light throughout the highly scattering medium of water and air particles. Scattering by these particles creates many well-known atmospheric optical ... -
Efficient Rendering of Human Skin
(The Eurographics Association, 2007)Existing offline techniques for modeling subsurface scattering effects in multi-layered translucent materials such as human skin achieve remarkable realism, but require seconds or minutes to generate an image. We demonstrate ... -
An Efficient Spatio-Temporal Architecture for Animation Rendering
(The Eurographics Association, 2003)Producing high quality animations featuring rich object appearance and compelling lighting effects is very time consuming using traditional frame-by-frame rendering systems. In this paper we present a rendering architecture ... -
Efficient Wavelet Rotation for Environment Map Rendering
(The Eurographics Association, 2006)Real-time shading with environment maps requires the ability to rotate the global lighting to each surface point's local coordinate frame. Although extensive previous work has studied rotation of functions represented by ... -
An Energy-Conserving Hair Reflectance Model
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a reflectance model for dielectric cylinders with rough surfaces such as human hair fibers. Our model is energy conserving and can evaluate arbitrarily many orders of internal reflection. Accounting for compression ... -
Enhancement of Bright Video Features for HDR Displays
(The Eurographics Association and Blackwell Publishing Ltd, 2008)To utilize the full potential of new high dynamic range (HDR) displays, a system for the enhancement of bright luminous objects in video sequences is proposed. The system classifies clipped (saturated) regions as lights, ... -
Enhancing and Optimizing the Render Cache
(The Eurographics Association, 2002)Interactive rendering often requires the use of simplified shading algorithms with reduced illumination fidelity. Higher quality rendering algorithms are usually too slow for interactive use. The render cache is a technique ...
