Or how to save and reuse radiosity

POV-Ray 3.5, 2002

This is a sample of a technique I'm using recently. After some posts on the POV-Ray newsgroups, I started testing this idea, and finally found a solution that works pretty well for me.

The idea consists on creating a "double version" of the scene: one with all the slow features turned off and used to save the radiosity data (wich I call "dummy scene"), and another for the final render, in wich the previously saved data is used. See the source code for more details...

Bellow is the dummy first-pass render, at 320x240, without aa.
