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.

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

(

)

const

Return the rotation associated with this transformation.

const Vector3D &

o

)

const

Transform.

		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)

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.
