[Numpy-discussion] Iterative Matrix Multiplication

Hi,
I have a list of vec3 lists (e.g. [[1,2,3],[4,5,6],[7,8,9],...]). To every
single one of the vec3 sublists, I am currently applying transformations. I
need to optimize this with numpy.
To get proper results, as far as I can tell, the vec3 lists must be
expressed as vec4s: [[1,2,3],[4,5,6],[7,8,9],...] ->
[[1,2,3,1],[4,5,6,1],[7,8,9,1],...]. Each of these needs to be multiplied
by either a translation matrix, or a rotation and translation matrix.
I don't really know how to approach the problem . . .
Thanks,
Ian
