yes, definitely

What are you allowed to do to the vectors?

the direction should be kept.

Those are shape vectors: each of them tells how to move some vertexes of

a trianguled mesh given a parameter.

I'll try to be a bit clearer: what I have is a trianguled mesh, a model.

It is defined as a base shape vector (just the coordinates of the v

vertices of the model) plus a linear combination of n shape vectors:

n

S = S0 + sum ( pi * Si )

i=1

now, the shape vectors that I have got are not orthonormal (as

requested) and I have no idea on how to make them so...

sorry I don't know if I got that
