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 ... -
Tensor Clustering for Rendering Many-Light Animations
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Rendering animations of scenes with deformable objects, camera motion, and complex illumination, including indirect lighting and arbitrary shading, is a long-standing challenge. Prior work has shown that complex lighting ... -
Sequential Monte Carlo Adaptation in Low-Anisotropy Participating Media
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents a novel method that effectively combines both control variates and importance sampling in a sequential Monte Carlo context. The radiance estimates computed during the rendering process are cached in a ... -
Irradiance Gradients in the Presence of Participating Media and Occlusions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we present a technique for computing translational gradients of indirect surface reflectance in scenes containing participating media and significant occlusions. These gradients describe how the incident ... -
Precomputed Atmospheric Scattering
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new and accurate method to render the atmosphere in real time from any viewpoint from ground level to outer space, while taking Rayleigh and Mie multiple scattering into account. Our method reproduces many ... -
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, ... -
Stylized Vector Art from 3D Models with Region Support
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We describe a rendering system that converts a 3D meshed model into the stylized 2D filled-region vector-art commonly found in clip-art libraries. To properly define filled regions, we analyze and combine accurate but ... -
Shallow Bounding Volume Hierarchies for Fast SIMD Ray Tracing of Incoherent Rays
(The Eurographics Association and Blackwell Publishing Ltd, 2008) -
Rendering Trees with Indirect Lighting in Real Time
(The Eurographics Association and Blackwell Publishing Ltd, 2008)High quality lighting is one of the challenges for interactive tree rendering. To this end, this paper presents a lighting model allowing real-time rendering of trees with convincing indirect lighting. Rather than defining ... -
iCheat: A Representation for Artistic Control of Indirect Cinematic Lighting
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Thanks to an increase in rendering efficiency, indirect illumination has recently begun to be integrated in cinematic lighting design, an application where physical accuracy is less important than careful control of scene ... -
Feature-guided Image Stippling
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents an automatic method for producing stipple renderings from photographs, following the style of professional hedcut illustrations. For effective depiction of image features, we introduce a novel dot ...
