cat-rom-spline's Issues

would you be open to a more memory friendly API refactor?

I'd like to use this module in one of my simulation loops but unfortunately it creates a lot of gc pressure because every invocation generates new array objects.

I'd like to have an API where a fixed array of points is passed in, which will significantly reduce the allocated memory on each invocation.
Open for suggestions, but I'm thinking something like this:

const out = new Array(100)  // hold up to 100 vec2s

for (let i=0; i < 100; i++)
    out[i] = [ 0, 0 ]

// returns the number of points that were generated in the spline.
// out is filled in with those values from 0...pointCount
const pointCount = catRomSpline(points, options, out)

Is this something you'd be open to?
