I'm trying to use openGL for 2D rendering. I have a basic function moving squares from one end of the screen to the other and repositioning them once they have gone off screen.
My problem is that I don't know how to get accurate representations of the screen in floating point values. Right now, -1.8f is the left side of my screen. I'm assuming this would only work for my own device. Am I correct?
How would I accurately find lets say, the bottom left of the screen?
