I'm just trying to make sure that the prof. developers play fair. As for your comments on 2nd Reality, the "scene" was divided into two camps - those who thought it was a great demo (it was), mainly because it was the best PC demo for ages (it was), and those who didn't think it was that great because it didn't have any original effects that weren't already present on the Amiga. I agree with both sides - it had a great flow and style, but as a programmer I wasn't amazed. > > o Bump-mapping (shaddup your face, Colin H! :O) > ^^^^^^^^^^^^^^^^^^^^^^^^^^^ > What does this mean?!?

Actually, Colin thought up a way of doing it using an 8 bit CLUT animation and practically zero CPU time, but neither of us have got around to implementing it - my claims of "I'll have it done tonight" have caused him to give me a bit of stick, and now he's accusing me of 'sub-contracting' the problem. Bump mapping is very rarely done in the 'realistic' way that a raytracer might do it (i.e. calculating the normals and perturbing them, etc). If you check the sources available, you'll probably find that a few clever applications of semi-trans textures would give an identical effect. -- == James_Russell@scee.sony.co.uk +44 (171) 447-1626 == Developer Support Engineer - Sony Computer Entertainment Europe Where there's a will, I want to be in it.
