Transformation3D IMP::algebra::Transformation3D::operator* | ( | const Transformation3D & | tr | ) | const |
Compose two rigid transformation such that for any vector v (rt1*rt2)*v = rt1*(rt2*v)

Transformation3D IMP::algebra::Transformation3D::operator/ | ( | const Transformation3D & | b | ) | const |
Compute the transformation which, when composed with b, gives *this.
That is a(x)== d(b(x)) for all x.
For consistency, this should probably have a nice name, but I don't know what name to give it.
