Detailed Description

The rotation is applied first, and then the point is translated.

Constructor & Destructor Documentation

IMP::algebra::Transformation3D::Transformation3D ( const Vector3D & t )

Construct a transformation with an identity rotation.

Definition at line 39 of file Transformation3D.h.

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)

Here is the call graph for this function:

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.
