Hi David, You are right there is much uniform variables can be changed in every frame but these all Built-in variables. I think this difference can change the state of your tenet.
I have read OrangeBook and Randi Rost ( GLSL GURU :) ) advices using uniform variables if you rarely update and in converse situation for attributes. I don't know why but if they advices, this must be true :) Regards. 2008/11/19 David Spilling <[EMAIL PROTECTED]> > Umit, > > Sorry to be picky, but: > > Firstly, uniform variables are intented to using in rarely changing >> values, and attributes is used while needing frequently changing values. >> > > Not quite.
