Detailed Description

Simple 3D transformation class.

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

See Also: IMP::core::Transform See geometric primitives for more information.

Constructor & Destructor Documentation

IMP::algebra::Transformation3D::Transformation3D ( )

construct an invalid transformation

Definition at line 34 of file Transformation3D.h.

IMP::algebra::Transformation3D::Transformation3D	(	const Rotation3D &	r,
		const Vector3D &	t = `Vector3D(0, 0, 0)`
	)

basic constructor

Definition at line 36 of file Transformation3D.h.

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

Construct a transformation with an identity rotation.

Definition at line 39 of file Transformation3D.h.

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 88 of file Transformation3D.h.

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

returns the rotation associated with this transformation

Definition at line 73 of file Transformation3D.h.

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

transform

Definition at line 43 of file Transformation3D.h.

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

returns the translation vector associated with this transformation

Definition at line 76 of file Transformation3D.h.

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

apply transformation (rotate and then translate)

Definition at line 47 of file Transformation3D.h.

Here is the call graph for this function:

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 50 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.
