Global Illumination for Interactive Applications and High-Quality Animations [article]

Cyrille Damez, Kirill Dmitriev, Karol Myszkowski
2002 Eurographics State of the Art Reports  
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.  ...

Interactive Global Illumination Using Implicit Visibility

Zhao Dong, Jan Kautz, Christian Theobalt, Hans-Peter Seidel
2007 15th Pacific Conference on Computer Graphics and Applications (PG'07)  
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  ...

Incremental Updates for Rapid Glossy Global Illumination

Xavier Granier, George Drettakis
2001 Computer graphics forum (Print)  
We build on a unified algorithm which uses hierarchical radiosity with clustering and particle tracing for diffuse and non-diffuse transport respectively.  ...  We present a new algorithm which chooses between reconstructing specular effects such as caustics on the diffuse radiosity mesh, or special purpose caustic textures, when high frequencies are present.  ...  Images of the three rooms of the house are shown in Fig. 6 These specular reflections are created through the unified hierarchical radiosity/particle tracing approach.  ...

Radiosity for dynamic scenes in flatland with the visibility complex

Rachel ORTI, Stephane RIVIERE, Fredo DURAND, Claude PUECH
1996 Computer graphics forum (Print)  
Previous methods have attempted to deal with dynamic environments (environments where the geometry, the material properties, etc., can change) but still suffer some limitations in the case of moving objects  ...  The radiosity method is particularly suitable for global illumination calculations in static environments.  ...  Shaw has applied hierarchical radiosity to dynamic environments.  ...

Using the visibility complex for radiosity computation [chapter]

Interactive update of global illumination using a line-space hierarchy

George Drettakis, François X. Sillion
1997 Proceedings of the 24th annual conference on Computer graphics and interactive techniques - SIGGRAPH '97  
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.  ...
