On Floating-Point Normal Vectors
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper we analyze normal vector representations. We derive the error of the most widely used representation, namely 3D floating-point normal vectors. Based on this analysis, we show that, in theory, the discretization ... -
On the Effective Dimension of Light Transport
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Light transport is often characterized within a high-dimensional space although practitioners have long known that it commonly behaves as a much lower-dimensional phenomenon. We study the effective dimension of light ... -
Online Construction of Surface Light Fields
(The Eurographics Association, 2005)We present a system for interactively capturing, constructing, and rendering surface light fields by incrementally building a low rank approximation to the surface light field. Each image is incorporated into the lighting ... -
Opacity Shadow Maps
(The Eurographics Association, 2001)Opacity shadow maps approximate light transmittance inside a complex volume with a set of planar opacity maps. A volume made of standard primitives (points, lines, and polygons) is sliced and rendered with graphics hardware ... -
Optimizing Color Matching in a Lighting Reproduction System for Complex Subject and Illuminant Spectra
(The Eurographics Association, 2003)This paper presents a technique for improving color matching results in an LED-based lighting reproduction system for complex light source spectra. In our technique, we use measurements of the spectral response curve of ... -
An Optimizing Compiler for Automatic Shader Bounding

Optimizing Disparity for Motion in Depth
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Beyond the careful design of stereo acquisition equipment and rendering algorithms, disparity post-processing has recently received much attention, where one of the key tasks is to compress the originally large disparity ... -
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 ... -
Out of Core Photon-Mapping for Large Buildings
(The Eurographics Association, 2005)This paper describes a new scheme for computing out-of-core global illumination in complex indoor scenes using a photon-mapping approach. Our method makes use of a cells-and-portals representation of the environment for ... -
Packet-based Hierarchal Soft Shadow Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Recent soft shadow mapping techniques based on back-projection can render high quality soft shadows in real time. However, real time high quality rendering of large penumbrae is still challenging, especially when multilayer ... -
Painting With Texture
(The Eurographics Association, 2006)We present an interactive texture painting system that allows the user to author digital images by painting with a palette of input textures. At the core of our system is an interactive texture synthesis algorithm that ... -
Parameterization-Aware MIP-Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a method of generating mipmaps that takes into account the distortions due to the parameterization of a surface. Existing algorithms for generating mipmaps assume that the texture is isometrically mapped to the ... -
Patch-based Texture Interpolation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we present a novel exemplar-based technique for the interpolation between two textures that combines patch-based and statistical approaches. Motivated by the notion of texture as a largely local phenomenon, ... -
Path differentials and applications
(The Eurographics Association, 2001)Photo-realistic rendering algorithms such as Monte Carlo ray tracing sample individual paths to compute images. Noise and aliasing artefacts are usually reduced by supersampling. Knowledge about the neighborhood of the ... -
Path Integration for Light Transport in Volumes
(The Eurographics Association, 2003)Simulating the transport of light in volumes such as clouds or objects with subsurface scattering is computationally expensive. We describe an approximation to such transport using path integration. Unlike the more commonly ... -
Path-space Motion Estimation and Decomposition for Robust Animation Filtering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Renderings of animation sequences with physics-based Monte Carlo light transport simulations are exceedingly costly to generate frame-by-frame, yet much of this computation is highly redundant due to the strong coherence ... -
A PCA Decomposition for Real-time BRDF Editing and Relighting with Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We propose a novel rendering method which supports interactive BRDF editing as well as relighting on a 3D scene. For interactive BRDF editing, we linearize an analytic BRDF model with basis BRDFs obtained from a principal ... -
Penumbra Maps: Approximate Soft Shadows in Real-Time
(The Eurographics Association, 2003)Generating soft shadows quickly is difficult. Few techniques have enough flexibility to interactively render soft shadows in scenes with arbitrarily complex occluders and receivers. This paper introduces the penumbra map, ... -
Per-Vertex Defocus Blur for Stochastic Rasterization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present user-controllable and plausible defocus blur for a stochastic rasterizer. We modify circle of confusion coefficients per vertex to express more general defocus blur, and show how the method can be applied to ... -
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 ...
