Add fromFunction
I'm not sure if this function logically fits with the rest of the module, but so far 99% of my quad usage is just creating a grid. Sometimes polar, sometimes rectangular, always a pain. This function just plugs [0, 1] x [0, 1] into a function you provide and spits out a simplicial complex with (optional) normals.
Sample usage:
quads.fromFunction((u, v) => [u, u + v], 10, 20)
// => grid with 10x20 quads and corners [0, 0], [1, 1], [0, 1], [1, 2]
No hard feelings if this is best left to a separate module!
Oops! I meant to include a flag for periodicity in the normal calculation (which is also common and a pain). A bit elaborate, but I think that's the extent of the features needed here. Again, can move elsewhere if desired :)
✅ done!
I'm starting to think this might be better as a standalone module (if it doesn't exist already). Additional big feature is the ability to compute attributes at the corresponding points or the normal analytically, both of which are a pain in the butt to work out after the fact. Could add that easily, but it starts to feel bloated in its current home.
Philosophically I want this module to be a collection of useful quad tools, so I don't mind if it grows a bit with some interesting things. I'm having a bit of trouble getting beyond the math speak, but it looks like this would be generating a parametric surface, which is exactly something I want to support. So even if you rip this out and put it in another module, I would probably provide an API entry point to use it.
