I’m about to write my very own scaling, rotation, normalization functions in python. Is there a convenient way to avoid this? I found NumPy, but it kind-a seems like an overkill for my little 2D-needs.
Are there basic vector operations available in the std python libs?
No, the standard in
numpy. I wouldn’t think of it as overkill, think of it as a very well written and tested library, even if you do just need a small portion of it. All the basic vector & matrix operations are implemented efficiently (falling back to C and Fortan) which makes it fast and memory efficient. Don’t make your own, use numpy.
