Radiosity Visualisation: radvis
'radvis' is a radiosity visualisation tool that illustrates matrix, progressive, and
hierarchical/wavelet radiosity in action. It started life as a debugging tool for my
radiosity code, and evolved from that into something I could use to
demonstrate the algorithms to other students.
These are some of the program's features:
- The current state of the solution and the current representation of the radiosity
matrix are updated as the solution progresses.
- The radiosity function over any patch can be plotted.
- Any element in the element hierarchy of the wavelet methods can be selected,
and the other elements in the scene that contribute radiosity to it displayed.
- Images of the solution or eps files of the mesh can be saved.
- The various parameters of the algorithms can all be adjusted using controls.
Currently, radvis is only built for the SGI. Its only dependencies are on OpenGL and
the xforms library, however, so it should be portable to most other unix platforms,
although without graphics hardware these may prove a little too slow to run it.
I have a linux port up and running which I hope to release soon: results on
a 200Mhz P6 seem promising.
You can
download radvis, and there is also some
documentation available.
