Global Illumination for Interactive Applications and High-Quality Animations
[article]
2002
Eurographics State of the Art Reports
Preserved Fulltext
Until now, this computational cost has prevented its widespread use in interactive design applications as well as in computer animations. ...
Recently, impressive advances have been made in both categories. ...
Forsyth et al. 22 first proposed an extension of hierarchical radiosity to update a converged hierarchical radiosity solution with respect to such a change. ...

Rendering global illumination effects for dynamic scenes at interactive frame rates is a computationally challenging task. ...
In this paper, we propose a global illumination approach for dynamic scenes that runs at near-real-time frame rates on a single PC. ...
There exist approaches to handle and make use of temporal coherence in dynamic scenes; a global illumination solution is incrementally updated by shooting negative light to compensate for changes in lighting ...

In the context of clustering for hierarchical radiosity, we introduce the idea of an implicit line-space hierarchy. ...
This hierarchy is realized by augmenting the links between hierarchical elements (clusters or surfaces) with shafts, representing the set of lines passing through the two linked elements. ...
In any hierarchical radiosity system, and in particular a clustering-based approach, the elements of the scenes are linked together following the potential interactions of light between such pairs. ...
