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.
Radvis is a unix program, although I'd like to port it to windows. Its
only dependencies are on OpenGL and the xforms library.
You can download
radvis, and there is also some documentation
available. It comes as part of the radiator package.
