What is the benefit of using screen coordinate space? I'm curious about why someone has designed this but not using the normalized coordinates.


Would it be efficient to calculate everything in normalized coordinate space and have the graphics pipeline do a transformation into screen coordinate space?


@SnackMixer The screen coordinates are necessary to actually output to the display/window - they're pixel coordinates.

@Ace Yeah, this is what happens in practice.


Just out of curiosity, why wouldn't screen coordinate set left bottom corner as origin


@wenere I think this is a holdover from CRT TVs when they when 'draw' the screen from top left. I think computer graphics held onto this convention.
