Bayesian Relighting
(The Eurographics Association, 2005)We present a simple method for relighting real objects viewed from a fixed camera position. Instead of setting up a calibrated measurement device, such as a light stage, we manually sweep a spotlight over the walls of a ... -
BendyLights: Artistic Control of Direct Illumination by Curving Light Rays
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In computer cinematography, artists routinely use non-physical lighting models to achieve desired appearances. This paper presents BendyLights, a non-physical lighting model where light travels nonlinearly along splines, ... -
Beyond Photorealism
(The Eurographics Association, 1999)For around 30 years the computer graphics research community has pursued photorealism as though it were the ultimate form of visual expression. Yet, as an art form, photorealism is one of many abstrations that an artist ... -
Bidirectional Importance Sampling for Direct Illumination
(The Eurographics Association, 2005)Image-based representations for illumination can capture complex real-world lighting that is difficult to represent in other forms. Current importance sampling strategies for image-based illumination have difficulties in ... -
Bidirectional Instant Radiosity
(The Eurographics Association, 2006)This paper presents a new sampling strategy to achieve interactive global illumination on one commodity computer. The goal is to propose an efficient numerical stochastic scheme which can be well adapted to a fast rendering ... -
Bilinear Accelerated Filter Approximation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Our method approximates exact texture filtering for arbitrary scales and translations of an image while taking into account the performance characteristics of modern GPUs. Our algorithm is fast because it accesses textures ... -
Bixels: Picture Samples with Sharp Embedded Boundaries
(The Eurographics Association, 2004)Pixels store a digital image as a grid of point samples that can reconstruct a limited-bandwidth continuous 2-D source image. Although convenient for anti-aliased display, these bandwidth limits irreversibly discard important ... -
BTF Compression via Sparse Tensor Decomposition
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, we present a novel compression technique for Bidirectional Texture Functions based on a sparse tensor decomposition. We apply the K-SVD algorithm along two different modes of a tensor to decompose it into a ... -
C-LOD: Context-aware Material Level-of-Detail applied to Mobile Graphics
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Attention-based Level-Of-Detail (LOD) managers downgrade the quality of areas that are expected to go unnoticed by an observer to economize on computational resources. The perceptibility of lowered visual fidelity is ... -
Capturing and Rendering With Incident Light Fields
(The Eurographics Association, 2003)This paper presents a process for capturing spatially and directionally varying illumination from a real-world scene and using this lighting to illuminate computer-generated objects. We use two devices for capturing such ... -
CC Shadow Volumes
(The Eurographics Association, 2004)We present a technique that uses culling and clamping (CC) for accelerating the performance of stencil-based shadow volume computation. Our algorithm reduces the fill requirements and rasterization cost of shadow volumes ... -
Characteristic Point Maps
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Extremely dense spatial sampling is often needed to prevent aliasing when rendering objects with high frequency variations in geometry and reflectance. To accelerate the rendering process, we introduce characteristic point ... -
A Closed-Form Solution to Single Scattering for General Phase Functions and Light Distributions
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Due to the intricate nature of the equation governing light transport in participating media, accurately and efficiently simulating radiative energy transfer remains very challenging in spite of its broad range of applications. ... -
Coherent Out-of-Core Point-Based Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We describe a new technique for coherent out-of-core point-based global illumination and ambient occlusion. Point-based global illumination (PBGI) is used in production to render tremendously complex scenes, so in-core ... -
Color Me Noisy: Example-based Rendering of Hand-colored Animations with Temporal Noise Control
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an example-based approach to rendering hand-colored animations which delivers visual richness comparable to real artwork while enabling control over the amount of perceived temporal noise. This is important both ... -
Colorization by Example
(The Eurographics Association, 2005)We present a new method for colorizing grayscale images by transferring color from a segmented example image. Rather than relying on a series of independent pixel-level decisions, we develop a new strategy that attempts ... -
Combined Rendering of Polarization and Fluorescence Effects
(The Eurographics Association, 2001)We propose a practicable way to include both polarization and fluorescence effects in a rendering system at the same time. Previous research in this direction only demonstrated support for either one of these phenomena; ... -
Combining Confocal Imaging and Descattering
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In translucent objects, light paths are affected by multiple scattering, which is polluting any observation. Confocal imaging reduces the influence of such global illumination effects by carefully focusing illumination and ... -
Combining Higher-Order Wavelets and Discontinuity Meshing: a Compact Representation for Radiosity
(The Eurographics Association, 2004)The radiosity method is used for global illumination simulation in diffuse scenes, or as an intermediate step in other methods. Radiosity computations using Higher-Order wavelets achieve a compact representation of the ... -
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 ...
