A Ray Tracing Approach to Diffusion Curves
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Diffusion curves [OBW*08] provide a flexible tool to create smooth-shaded images from curves defined with colors. The resulting image is typically computed by solving a Poisson equation that diffuses the curve colors to ... -
Direct Ray Tracing of Phong Tessellation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)There are two major ways of calculating ray and parametric surface intersections in rendering. The first is through the use of tessellated triangles, and the second is to use parametric surfaces together with numerical ... -
Importance Point Projection for GPU-based Final Gathering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a practical importance-driven method for GPU-based final gathering. We take as input a point cloud representing directly illuminated scene geometry; we then project and splat the points to microbuffers, which ... -
Least Squares Vertex Baking
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We investigate the representation of signals defined on triangle meshes using linearly interpolated vertex attributes. Compared to texture mapping, storing data only at vertices yields significantly lower memory overhead ... -
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 ... -
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 ... -
Progressive Expectation-Maximization for Hierarchical Volumetric Photon Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2011)State-of-the-art density estimation methods for rendering participating media rely on a dense photon representation of the radiance distribution within a scene. A critical bottleneck of such kernel-based approaches is the ... -
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 ... -
A Physically Plausible Model for Light Emission from Glowing Solid Objects
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The emissive properties of glowing solid objects appear to be something that the graphics community has not considered in depth before. While the volumetric emission of plasma, i.e. flames, has been discussed numerous ... -
Perceptual Global Illumination Cancellation in Complex Projection Environments
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The unintentional scattering of light between neighboring surfaces in complex projection environments increases the brightness and decreases the contrast, disrupting the appearance of the desired imagery. To achieve ... -
Anaglyph Stereo Without Ghosting
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Anaglyph stereo provides a low-budget solution to viewing stereoscopic images. However, it may suffer from ghosting and bad color reproduction. Here we address the first issue. We present a novel technique to perceptually ... -
Perception of Visual Artifacts in Image-Based Rendering of Façades
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Image-based rendering (IBR) techniques allow users to create interactive 3D visualizations of scenes by taking a few snapshots. However, despite substantial progress in the field, the main barrier to better quality and ... -
ManyLoDs: Parallel Many-View Level-of-Detail Selection for Real-Time Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Level-of-Detail structures are a key component for scalable rendering. Built from raw 3D data, these structures are often defined as Bounding Volume Hierarchies, providing coarse-to-fine adaptive approximations that are ... -
Silhouette-Aware Warping for Image-Based Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Image-based rendering (IBR) techniques allow capture and display of 3D environments using photographs. Modern IBR pipelines reconstruct proxy geometry using multi-view stereo, reproject the photographs onto the proxy and ... -
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 ... -
Improved Stochastic Progressive Photon Mapping with Metropolis Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents an improvement to the stochastic progressive photon mapping (SPPM), a method for robustly simulating complex global illumination with distributed ray tracing effects. Normally, similar to photon mapping ... -
Stone Weathering in a Photograph
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The appearance of weathering effects on stone is important for creating outdoor scenes in computer graphics. To achieve them, previous research has built upon physical simulation, which, while yielding a degree of realism, ... -
Stratified Sampling for Stochastic Transparency
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The traditional method of rendering semi-transparent surfaces using alpha blending requires sorting the surfaces in depth order. There are several techniques for order-independent transparency, but most require either ... -
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 ... -
Optimizing Environment Maps for Material Depiction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present an automated system for optimizing and synthesizing environment maps that enhance the appearance of materials in a scene. We first identify a set of lighting design principles for material depiction. Each principle ...
