No. Imagine someone reading a piece of code that represents surface normals
and pick rays as a Point3D, not very understandable. Also it's useful to
compute angles between vectors, cross product, magnitude of the vector, ...

Not sure, it's been a while since I've worked with 3d graphics libraries.
Java3d has this methods on the Transform3d class.

Thanks, cheers,
