This is a little demo that imports and exports vertex-colored meshes using my own simple file format (*.radio). I wrote it because I wanted to know how vertex colors were stored in the mesh (and I needed this info in order to write my Caligari OBJ export script). So now I can export radiosity solutions from blender to trueSpace. But I don’t need (or want) to do that, it was just an exercise.
You can use this demo to read and write such meshes. If you press: VKEY, WKEY, ENTER, you will smooth out the vertex colors (try it on the knot and sphere). I’ve included some nice sample objects to get you started:
This script uses the GUI module of 2.23, which is gone in 2.25! Why did they get rid of it?
