Fidning the coordinates of the edges of the screen
Author
I know this sounds dumb, but I can''t figure out how to find out the coordinates of the edges of the screen. I initally thought that it was a set number, but I guess not. Is there a formula?

a2k: glViewport should be called in the same way regardless of whether you''re going to setup an orthographic projection or a perspective projection. It provides the mapping from normalized device coordinates to window coordinates.
griffenjam: It depends on how you setup your projection matrix.

I set up my projection like this.
gluPerspective(45.0f,(GLfloat)glWidth/(GLfloat)
glHeight,0.1f,1000.0f);
Now, given the current depth can you figure out the displayable width and height?
