It's not much reinventing the wheel -- a 3d vector/matrix/quaternion
library without optimizations can be written in under a week, the main
work of the proposal would be data structures and algorithms that
would be built over it.

There are some problems with naming conventions ( as to the standard
used in CG3D ), and also the fact that only the point class (and maybe
segment) would be of any use to me. However this is compelling, as I
would be working on the things I planned from almost scratch anyway,
but from the outside it would look like expanding something existing
