Using tLink3D surly will make the computatons more effective, however
calculating the vector between to points and its length (as tLink
does) is not my real problem, the problem is more, how to correctly
use this information to draw correct rotations in Gem. 

In 2D (polar coordinates) this is simple, but I still haven't found a
way to add the missing rotation to go from polar/cartesian to
spherical coordinates.
