This script imports Radiosity files to Blender.

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>
|

Execute this script from the "File->Import" menu and choose a Radiosity

file to open.
