Transformation2D IMP::algebra::Transformation2D::operator* | ( | const Transformation2D & | tr | ) | const |
\ note The transformations are composed such that for any vector v (rt1*rt2)*v = rt1*(rt2*v)

Transformation2D IMP::algebra::Transformation2D::operator/ | ( | const Transformation2D & | b | ) | const |
Compute the transformation d which, when composed with b, gives this one. That is a(x)== d(b(x)) for all x.
