Perceptually-driven decision theory for interactive realistic rendering

Reynald Dumont, Fabio Pellacini, James A. Ferwerda
2003 ACM Transactions on Graphics  
The approach uses efficient perceptual metrics within a decision theoretic framework to optimally order rendering operations, producing images of the highest visual quality within system constraints.  ...  We demonstrate the usefulness of this approach for various applications such as diffuse texture caching, environment map prioritization and radiosity mesh simplification.  ...  Thanks to Peggy Andersen for proofreading the paper multiple times and Jeremy Selan for technical help. Special thanks to Don Greenberg for his unconditional support during tough times.  ...

State of the Art in Perceptually Driven Radiosity [article]

J. Prikryl, W. Purgathofer
1998 Eurographics State of the Art Reports  
We will not speak about importance-driven radiosity solutions, as those methods are based on using geometric visibility rather than on using human perception-aware techniques.  ...  In the second part of the report we concentrate on known radiosity methods that already use these perceptual approaches to predict different visible errors of the result of the radiosity computation.  ...  His main research topic is perceptual approaches to radiosity solutions.  ...

Texture-based visibility for efficient lighting simulation

Cyril Soler, F. X. Sillion
2000 ACM Transactions on Graphics  
A new refinement algorithm is proposed, that chooses the most appropriate technique to compute the energy transfer and resulting radiosity distribution for each receiver/emitter configuration.  ...  Lighting simulations obtained using hierarchical radiosity with clustering can be very slow when the computation of fine and artifact-free shadows is needed.  ...  We also would like to thank the referees for their useful comments and suggestions.  ...

Tighter error bounds and weighted error metrics for hierarchical radiosity

Chin‐Chen Chang, Zen‐Chung Shih
1998 Journal of Visualization and Computer Animation  
In this paper we first derive a tighter error bound on form factors as a subdivision criterion for the hierarchical radiosity algorithm.  ...  Such an error bound can reduce more unnecessary links and improve the performance of the hierarchical radiosity algorithm to meet a user-specified error tolerance.  ...  We would like to thank reviewers for their helpful suggestions.  ...

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

Cyrille Damez, Kirill Dmitriev, Karol Myszkowski
2002 Eurographics State of the Art Reports  
One of the main obstacles to the use of global illumination in image synthesis industry is the considerable amount of time needed to compute the lighting for a single image.  ...  Several algorithms have been proposed to address these issues. In this report, we present a much needed survey and classification of the most up-to-date of these methods.  ...  Thanks also to all those who read early drafts of the paper -Philippe Bekaert, Katja Daubert, Jörg Haber, Vlastimil Havran, Jan Kautz, Annette Scheel, and Philipp Slusallek for their help-  ...

Disruptive Technologies in Computer Graphics: Past, Present, and Future [article]

Donald P. Greenberg
1999 Symposium on Rendering  
During the 1970's, only the very costly and specialized hardware used for military and aerospace simulations was capable of real-time surface color display.  ...  In the early 1970's expensive color frame buffers with the capability for displaying static color images were introduced.  ...  It was not until 1979 that Whitted's ray tracing algorithm was published, and Cornell's first radiosity images appeared in 1984.  ...

Selective rendering

Alan Chalmers, Kurt Debattista, Luis Paulo dos Santos
2006 Proceedings of the 4th international conference on Computer graphics and interactive techniques in Australasia and Southeast Asia - GRAPHITE '06  
A key factor to consider if we are ever to achieve so-called "Realism in Real-Time", is that we are computing images for humans to look at.  ...  The computational requirements of a full physically-based global illumination solution are significant, currently precluding its solution on even a powerful modern PC in reasonable let alone real time.  ...  We would also like to thank Veronica Sundstedt for the use of the corridor model.  ...
