[vtkusers] How to get angle between two 3D points

[Marco Sambin]

Hi.
In order to define an angle, you will need at least THREE points. Is the
third point the origin (0,0,0) in your case?
I guess you will need to identify the plane "containing" those three
points, and then you will be able to compute the angle on that plane, in a
"2D fashion".
Regards,

Marco
