How would I go about rendering a game object (3d model in this case) but only if it is in a certain area of the screen (eg middle 30% of screen).
I want to have something render only if its center is withing the bounds of a the screen middle lets say my screen is 480pixels height (example but need it to be resolution independent) and i want it to show only if its position is between(screen height) of 168 and 312.
