I haven't find a way to genarate texture coordinates (s,t,r,q) as texgen() does in GL ... But maybe there is another way to do it , or maybe with Perf 1.2 ???

I have a Performer demo which uses both spotlights and shadows which I will eventually clean up and ship sometime. In the future (possibly 1.3) we will directly support projected lights and shadows.

I noticed that the ONYX demo was very small, about 49K. Can you release the code for the demo or does someone have code for Projected Texture, I was particularly interested in the Spotlight screen shot, I would like to implement something like that I my project.

I've seen the 'projtex' demo and have taken a look at the source. Does anyone know of documentation concerning texture projection and the theory behind it? Has anyone attempted or been successful with aircraft landing light lobes? Thanks =========================================================================== 'Bwana' Bob Buckley CTA, Inc.
