CGAL users discussion list

Hello all,

There's Aff_transformation_3 and Aff_transformation_2 in CGAL perform
affine transformation. But I don't know how to perform such a conversion
using CGAL:

Given 3 points in 3D space, say A, B and C, I need to construct a 
'user coord system' in this manner: use A as the origin of the new system,
vector AB to be along the x axis, z axis pass through A and extends to the 
normal direction of the plane determined by the 3 points.

with such a user system, then I will perform coord transformation from 
the default system to this user system and vice versa.

Thanks for any help.
