This script exports meshes to Radiosity file format.
The Radiosity file format is my own personal format. I created it to
learn how meshes and vertex colors were stored. See IO-Examples.zip, the
example *.radio files on my web page.
Usage:<br>
Select meshes to be exported and run this script from "File->Export" menu.
Notes:<br>
Before exporting to .radio format, the mesh must have vertex colors.
Here's how to assign them:
1. Use radiosity!
2. Set up lights and materials, select a mesh, switch the drawing mode
to "textured," press the VKEY.
3. Press the VKEY and paint manually.
4. Use a custom script to calculate and apply simple diffuse shading and
specular highlights to the vertex colors.
5. The Videoscape format also allows vertex colors to be specified.
