[Fluxus] Mapping question

i'm not sure what you are trying to do, but i think you need to render 
your scene into a pixel primitive and map its texture to the 3d model of 
the environment you want to project on. good example is dave's 
planetarium module and the planetarium.scm in the example folder that 
uses it.

i don't think that's possible.

> And finally, the big question : How to make a mask to not project on unmapped zone?
you either make your environment model not to cover the area you don't 
want to project on, or you might try a 2d overlay texture, which draws 
over the unwanted areas with black.
