I'm not quite sure what you want, but I have a generic package for working
with points and vectors. It contains functions such as:

   function "+" (Left  : Point;
                 Right : Vector) return Point;

   function "-" (Left, Right : Point) return Vector;

In addition to that did I write a 3D specific package with a vector product
(and probably something else too).

Is it something like that? (Or are somebody else interested in what I
described?)

Greetings,

Jacob
