Hey, When working with projective texturing, what is the different between GL_EYE_PLANE & GL_OBJECT_PLANE? And how do I use them propably? Which would you suggest, when I would like to project a spot light...

I believe you need to use GL_EYE_PLANE for projective texturing. GL_OBJECT_PLANE creates texcoords for the object about the object's origin, but this isn't what you want for projective texturing. Check out this document on projective texturing: Projective Texture Mapping...

My opinion is a recombination and regurgitation of the opinions of those around me. I bring nothing new to the table, and as such, can be safely ignored.[ Useful things - Firefox | GLee | Boost | DevIL ]

The RedBook also has a very good, very simple code sample.
