www.nvidia.com/developer (http://www.nvidia.com/developer)

haven't been there in a while *cough, been actually making a game*, but they have some really good stuff..

i can't wait till true displacements maps make it into hardware though.
maybe for the playstation 3 http://www.opengl.org/discussion_boards/ubb/smile.gif

you should check the archives of this board as well.
some good talks on getting point lights to work correctly, etc..
here's a little demo i wrote up real quick.. http://www.angelfire.com/ab3/nobody/pplRendering.html

your going to need code to calculate tangents, and just in case you havent' coded it up yet.. http://www.angelfire.com/ab3/nobody/calc_tangent.c

that's some.

btw, this rendering technique is pretty useless if your making a pc game.
unless your id software or somethin.


laterz.

I have been working on some consoles, and I always feel sorry that I can not use per pixel lighting on console platform(XBOX can do it, but I have not get my hand on it yet), so I am quite excited by the last sentence from kaber0111. Are you talking about some per pixel lighting method that can be used on console? Can you give more details? btw, the 2 links you given do not work for me http://www.opengl.org/discussion_boards/ubb/smile.gif

I think he was talking about XBOX. The thing with the PC is, if you want to do per-pixel lighting, you can only do it for a few cards. Probably 95% of users dont have a card that supports the necessary features. So in the end, you either make a game that only works for 5% of the users, or you make it so you can toggle ppl on/off and do all that work for a feature 95% of users wont use.
