[vtkusers] Alignment 3-2-1

[David Català]

hello everybody,

Anybody knows how to make an alignment with 6 points: 3 points define
a plane, 2 points define a line? This alignment is called RPS
(Reference Point System).

I need to know algorithm or math basis of that,(3-2-1 method, i think
it is)

Any help is welcome.
Thanks,

David Català
