Hi all
First as I’m new let me say hi to you all. I’ve been coding in OpenGL on and off for about a year now and am currently programming a game engine.
I’ve been unable as of yet to implement or even understand the first thing about projective textures. I have read numerous resources about them and even have a book which covers them. None I can understand it from.
As it appears (and please correct me if I’m wrong), there is parallel and perspective texture projection. I am pretty sure how each look.
After that, the matrix stuff throws me off and I can’t follow it. Also, there is this Q texture coordinate or something. All of this confuses me quite a lot!
Would it be possible for someone to outline steps (possibly with example code)? I tend to learn best looking a code (or pseudo code) than with theory.
Thank you,
Lprogster
