Hi, anyone know how to setup the projection matrix (using orthogonal projection) in order to have that an increment of 1.0f in OpenGL coordinates on the scene will correspond to an increment of 1 pixel on the screen? Thanks!

What is wrong with glOrtho(0, pixels_wide, 0, pixels_high, -1, 1)?

If you want to figure out how to manually create that matrix, take a look at the man page for glOrtho.


Nothing: I'm just a bit rusty... Well, maybe MUCH more than a bit. Thanks!
