Not really. Youtuber Acerola has a great series on shader programming and dealing with negative numbers is a non-factor. The advantage of working with computers is that it abstracts that complexity away. You program with high level concepts, a dev rarely deals with direct calculations, unless they are actually writing the fundamental apis for it, like DX or Vulkan. Much less copy-paste formulas. It gets complicated fast, but the abstraction keeps it simple for the developer, like, the math is perhaps the easiest part of programming computer graphics.
Ace is a decent watch. Shit post quality video energy, that's information dense. Always gonna second an Acerola suggestion.
It's okay. The equations have been done since a long time ago. Devs don't have to think about it much. Essentially, computer simulations already have their own body of math that you probably were not taught in physics, because they aren't relevant for real world physics study.
Yeah, and you probably used libraries that abstracted the math away so you could focus on your simulations instead of thinking about transforming negative signs for the GPUs. That's already figured out.
