projection matrix question for tom

hi there,
i am experiencing exactly the same problem as the one you reported in this post:

http://www.opengl.org/discussion_boards/cgi_directory/ultimatebb.cgi?ubb=get_topic;f=3;t=009260

now the question is, did you ever get it fixed in some way?

thanks for any help you may provide

If I recall correctly, the app I was working on at the time is this one:
http://www.delphi3d.net/download/npr_toon.zip

What I ended up doing is to change the order of operations such that the problem no longer occured.

so it never got fixed really
i’ve decided to bypass the problem using the modelview matrix only but it’s somehow scaring to know that push/pop projection matrix does not preserve invariance

thanks for your reply
