Light Field Techniques for Reflections and Refractions
(The Eurographics Association, 1999)
Reflections and refractions are important visual effects that have long been considered too costly for interactive applications. Although most contemporary graphics hardware supports reflections off curved surfaces in the ...
Interactive Rendering of Translucent Deformable Objects
(The Eurographics Association, 2003)
Realistic rendering of materials such as milk, fruits, wax, marble, and so on, requires the simulation of subsurface scattering of light. This paper presents an algorithm for plausible reproduction of subsurface scattering ...
Convolution Shadow Maps
(The Eurographics Association, 2007)
We present Convolution Shadow Maps, a novel shadow representation that affords efficient arbitrary linear filtering of shadows. Traditional shadow mapping is inherently non-linear w.r.t. the stored depth values, due to the ...
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 ...
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 ...
An Efficient Spatio-Temporal Architecture for Animation Rendering
(The Eurographics Association, 2003)
Producing high quality animations featuring rich object appearance and compelling lighting effects is very time consuming using traditional frame-by-frame rendering systems. In this paper we present a rendering architecture ...
Interactive Global Illumination Using Selective Photon Tracing
(The Eurographics Association, 2002)
We present a method for interactive global illumination computation which is embedded in the framework of Quasi-Monte Carlo photon tracing and density estimation techniques. The method exploits temporal coherence of ...
Spherical Harmonic Gradients for Mid-Range Illumination
(The Eurographics Association, 2004)
Spherical harmonics are often used for compact description of incident radiance in low-frequency but distant lighting environments. For interaction with nearby emitters, computing the incident radiance at the center of an ...
Image-Based Reconstruction of Spatially Varying Materials
(The Eurographics Association, 2001)
The measurement of accurate material properties is an important step towards photorealistic rendering. Many real-world objects are composed of a number of materials that often show subtle changes even within a single ...
