Question: What was graphics programming like in early versions of Mac OS or Windows? Before GPUs became mainstays?
Who can tell me?
Having gained an understanding of what computer graphics involves, creating GUIs on 1980s or early 90s CPUs seems like quite the accomplishment!
@alcinnz The most tedious part is that there was no compositor. When a window was moved and part of your application window was exposed as a result, you were handed the coordinates and expected to redraw that part of your window, and not anything that was now covered up.
@mathew Ouch! That'd be asking for bugs!
@alcinnz Yep. Developers used to refer to "mouse turds" from dragging things across application windows and the redraw having fencepost errors and the like.
