OK, thanks.
In fact, it's a "visual" method to see a set of points with the better
view (maximum of variance).
It's like to swivel a cube around to see all of its sides ... but this
in more than 3D.
When I show points in differents planes (F1-F2, F2-F3, F2-F4 ... for
example), I make rotations, isn't it ?
I think I have understand the principle, and I don't forget to consult
the books you (all) recommended to me.
Sincerly, Nico.
PS : Excuse me for my english but I'm french (Lyon) and I am not used to
write or speak english.
