Nope--I need the same matrix applied to each vector.
Because 3D translation matrices must, if I understand correctly be 4x4, the
vectors must first be changed to length 4 (adding a 1 for the last term).
Then, the matrices would be applied. Then, the resulting n*4 array would be
converted back into a n*3 array (simply by dropping the last term).
