Multiplying transformation matrix with multiple vectors.

[5nefarious]

Is there a way to put a bunch of Vec3s in an 3xN matrix, so that I can transform all of them with a single matrix multiplication?

There isn't currently, but it would be a good thing to have. The main question is what to do with the results. The easy option would be to mutate the input but it might also be desirable to support a separate output.

I guess this could be handled by Rust iterators, e.g. something like

vec3s.iter().map(|v| m.transform_point3(v)).collect()

or to mutate the input

vec3s.iter_mut().for_each(|v| *v = m.transform_point3(*v));
