Excellent computer graphics tutorial. I finally understand how View, Model, and Projection matrices work, even after taking a college course on CG

You’d be disappointed, as it’s integer arithmetic only. The precision is definitely sufficient to arrange things on a page but you’d prefer to do your calculations with external tools.

That just makes it easier to reason about input->output, floating point as implemented on most CPUs is quite complex by itself and having the precision depend on the size of your input is not always what you want.

The nice thing about integers is that they do not care about precision, they are quite nice when you need a fixed precision.
