Canned Lightsources
Complex luminaries and lamp geometries can greatly increase the realism of synthetic images. Unfortunately, the correct rendering of illumination from complex lamps requires costly...

Global Ray-Bundle Tracing with Hardware Acceleration
The paper presents a single-pass, view-dependent method to solve the general rendering equation, using a combined finite element and random walk approach. Applying finite element t...

Three Point Clustering for Radiance Computations
Abstract. There has been great success in speeding up global illumination computation in diffuse environments. The concept of clustering allows radiosity computations even for scen...

Automatic Calculation of Soft Shadow Textures for Fast, High-Quality Radiosity
We propose a new method for greatly accelerating the computation of complex, detailed shadows in a radiosity solution. Radiosity is computed using a "standard" hierarchi...

Per-Object Image Warping with Layered Impostors
Image warping is desirable in the context of image-based rendering because it increases the set of viewpoints for which a single image can be used. This paper proposes a method for...

A New Change of Variables for Efficient BRDF Representation
We describe an idea for making decomposition of Bidirectional Reflectance Distribution Functions into basis functions more efficient, by performing a change-of-variables transform...

Efficient Image Generation for Multiprojector and Multisurface Displays
We describe an efficient approach to rendering a perspectively correct image on a potentially irregular display surface that may be illuminated with one or more distinct devices. T...

Interactively Modeling with Photogrammetry
We describe an interactive system to reconstruct 3D geometry and extract textures from a set of photographs taken with arbitrary camera parameters. The basic idea is to let the use...

Lazy Decompression of Surface Light Fields for Precomputed Global Illumination
This paper describes a series of algorithms that allow the unconstrained walkthrough of static scenes shaded with the results of precomputed global illumination. The global illumin...

Fidelity of Graphics Reconstructions: A Psychophysical Investigation
In this paper we develop a technique for measuring the perceptual equivalence of a graphical scene to a real scene. Ability to compare images is valuable in computer graphics for a...
