I was wondering how I can position a couple of videoplanes on a pixel-
accurate position within an opengl environment.
Here's the thing : I have a background image (on a videoplane filling
the screen), with 2 holes cut out, using alphachannels. I know where
and how big these holes are in pixels, but how do I translate this to
opengl so I can position 2 other videoplanes on the exact location?
Trial and error gives me the right spot, but there's got to be someway
to do this without guessing, right?
