Compact, Fast and Robust Grids for Ray Tracing
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
The focus of research in acceleration structures for ray tracing recently shifted from render time to time to image, the sum of build time and render time, and also the memory footprint of acceleration structures now ...
Exploiting Visibility Correlation in Direct Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
The visibility function in direct illumination describes the binary visibility over a light source, e.g., an environment map. Intuitively, the visibility is often strongly correlated between nearby locations in time and ...
Lazy Solid Texture Synthesis
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Existing solid texture synthesis algorithms generate a full volume of color content from a set of 2D example images. We introduce a new algorithm with the unique ability to restrict synthesis to a subset of the voxels, ...
Ptex: Per-Face Texture Mapping for Production Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Explicit parameterization of subdivision surfaces for texture mapping adds significant cost and complexity to film production. Most parameterization methods currently in use require setup effort, and none are completely ...
Real-time Shading with Filtered Importance Sampling
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We propose an analysis of numerical integration based on sampling theory, whereby the integration error caused by aliasing is suppressed by pre-filtering. We derive a pre-filter for evaluating the illumination integral ...
An Analysis of the In-Out BRDF Factorization for View-Dependent Relighting
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Interactive rendering with dynamic natural lighting and changing view is a long-standing goal in computer graphics. Recently, precomputation-based methods for all-frequency relighting have made substantial progress in this ...

Table-driven Adaptive Importance Sampling
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Monte Carlo rendering algorithms generally rely on some form of importance sampling to evaluate the measurement equation. Most of these importance sampling methods only take local information into account, however, so the ...
Frame Sequential Interpolation for Discrete Level-of-Detail Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
In this paper we present a method for automatic interpolation between adjacent discrete levels of detail to achieve smooth LOD changes in image space. We achieve this by breaking the problem into two passes: We render the ...
Geometry-Aware Framebuffer Level of Detail
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
This paper introduces a framebuffer level of detail algorithm for controlling the pixel workload in an interactive rendering application. Our basic strategy is to evaluate the shading in a low resolution buffer and, in a ...
