So far from all the tutorials I've done, all coordinates for stuff on the screen have been in terns of normalized device coordinates. (i.e. everything is between -1 and 1). I want to try to make a game, however, it seems like a nightmare to make all of my coordinates floats between -1 and 1.
What's the most common way to place objects in a world? Say I want a grid of 9 cubes... do I really have to calculate normalized floating point values for every vertex or can I have some sort of world coordinate system that I then transform to ndc?
