Real Illumination from Virtual Environments
(The Eurographics Association, 2005)
We introduce a method for actively controlling the illumination in a room so that it is consistent with a virtual world. In combination with a high dynamic range display, the system produces both uniform and directional ...
Table-top Computed Lighting for Practical Digital Photography
(The Eurographics Association, 2005)
We apply simplified image-based lighting methods to reduce the equipment, cost, time, and specialized skills required for high-quality photographic lighting of desktop-sized static objects such as museum artifacts. We place ...
Adaptive Numerical Cumulative Distribution Functions for Efficient Importance Sampling
(The Eurographics Association, 2005)
As image-based surface reflectance and illumination gain wider use in physically-based rendering systems, it is becoming more critical to provide representations that allow sampling light paths according to the distribution ...
Stippling and Silhouettes Rendering in Geometry-Image Space
(The Eurographics Association, 2005)
We present a novel non-photorealistic rendering method that performs all operations in a geometry-image domain. We first apply global conformal parameterization to the input geometry model and generate corresponding geometry ...
A Low Dimensional Framework for Exact Polygon-to-Polygon Occlusion Queries
(The Eurographics Association, 2005)
Despite the importance of from-region visibility computation in computer graphics, efficient analytic methods are still lacking in the general 3D case. Recently, different algorithms have appeared that maintain occlusion ...
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 ...
Radiance Cache Splatting: A GPU-Friendly Global Illumination Algorithm
(The Eurographics Association, 2005)
Fast global illumination computation is a challenge in several fields such as lighting simulation and computergenerated visual effects for movies. To this end, the irradiance caching algorithm is commonly used since it ...
Interactive System for Dynamic Scene Lighting using Captured Video Environment Maps
(The Eurographics Association, 2005)
We present an interactive system for fully dynamic scene lighting using captured high dynamic range (HDR) video environment maps. The key component of our system is an algorithm for efficient decomposition of HDR video ...
Ray Maps for Global Illumination
(The Eurographics Association, 2005)
We describe a novel data structure for representing light transport called ray map. The ray map extends the concept of photon maps: it stores not only photon impacts but the whole photon paths. We demonstrate the utility ...
Estimation of 3D Faces and Illumination from Single Photographs Using A Bilinear Illumination Model
(The Eurographics Association, 2005)
3D Face modeling is still one of the biggest challenges in computer graphics. In this paper we present a novel framework that acquires the 3D shape, texture, pose and illumination of a face from a single photograph. ...
