Hi,
I’ve posted my problem with code, pictures, and comments here:
http://www.auriga3d.org/problem/
Basically I am using point sprites and texture coordinate replacement state change (GL_COORD_REPLACE_ARB). I attempt to reset the texture unit state by setting GL_COORD_REPLACE_ARB to false, but after the 1st time I call the point sprite render function I get this weird texture warping artifact for all other rendering. I would like to find out how to properly reset the texture unit state to prevent this artifact; apparently setting GL_COORD_REPLACE_ARB to false is not enough…
Thanks…
