Definition at line 45 of file Transformation3D.h.

## Member Function Documentation

 bool IMP::algebra::Transformation3D::get_is_valid ( ) const
Returns
true if the 3D transformation is valid; false if the transformation was initialized only with the empty constructor, or it was initialized with an invalid rotation.

Definition at line 113 of file Transformation3D.h.

 const Rotation3D& IMP::algebra::Transformation3D::get_rotation ( ) const

Return the rotation associated with this transformation.

Definition at line 98 of file Transformation3D.h.

 Vector3D IMP::algebra::Transformation3D::get_transformed ( const Vector3D & o ) const

Transform.

Definition at line 49 of file Transformation3D.h.

 void IMP::algebra::Transformation3D::get_transformed_adjoint ( const Vector3D & v, const Vector3D & Dw, Vector3D * Dv, Transformation3DAdjoint * DT ) const

Get adjoint of inputs to get_transformed from adjoint of output.

Compute the adjoint (reverse-mode sensitivity) of input vector to get_transformed and this transformation from the adjoint of the output vector.

 TransformedVector3DAdjoint IMP::algebra::Transformation3D::get_transformed_adjoint ( const Vector3D & v, const Vector3D & Dw ) const

Get adjoint of inputs to get_transformed from adjoint of output.

Compute the adjoint (reverse-mode sensitivity) of input vector to get_transformed and this transformation from the adjoint of the output vector.

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

Return the translation vector associated with this transformation.

Definition at line 101 of file Transformation3D.h.

 Vector3D IMP::algebra::Transformation3D::operator* ( const Vector3D & v ) const

Apply transformation (rotate and then translate)

Definition at line 72 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)

Definition at line 75 of file Transformation3D.h. 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.
