Constructor & Destructor Documentation

IMP::algebra::ReferenceFrame3D::ReferenceFrame3D ( )

Create the default reference frame.

That is, the origin with x,y,z axis as the principal axes.

IMP::algebra::ReferenceFrame3D::ReferenceFrame3D ( const Transformation3D & tr )

explicit

A reference frame specified by a transformation matrix.

Constructs a reference frame using transformation tr

Parameters

tr	a transformation from local coordinates in this constructed reference frame to the global coordinates (equiv., tr brings the origin of the global frame to the origin of this frame, in global coordinates),

Definition at line 66 of file ReferenceFrame3D.h.

Vector3D IMP::algebra::ReferenceFrame3D::get_global_coordinates ( const Vector3D & v ) const

Convert the vector v from local to global coordinates (i.e., v is specified in this reference frame)

Definition at line 88 of file ReferenceFrame3D.h.

ReferenceFrame3D IMP::algebra::ReferenceFrame3D::get_global_reference_frame ( const ReferenceFrame3D & v ) const

Convert reference frame v from local to global (i.e., v is specified in this reference frame)

Definition at line 100 of file ReferenceFrame3D.h.

Vector3D IMP::algebra::ReferenceFrame3D::get_local_coordinates ( const Vector3D & v ) const

Convert the vector v from global to local coordinates (i.e., the returned vector is specified in this reference frame)

Definition at line 94 of file ReferenceFrame3D.h.

ReferenceFrame3D IMP::algebra::ReferenceFrame3D::get_local_reference_frame ( const ReferenceFrame3D & v ) const

Convert reference frame v from global to local (i.e. the returned reference frame is speficied in this reference frame)

Definition at line 106 of file ReferenceFrame3D.h.

const Transformation3D& IMP::algebra::ReferenceFrame3D::get_transformation_from ( ) const

Return the transformation from global to local coordinates.

Get the transformation from the origin of this reference frame to the origin of the global frame (both in global coordinates).

Definition at line 82 of file ReferenceFrame3D.h.

const Transformation3D& IMP::algebra::ReferenceFrame3D::get_transformation_to ( ) const

Return transformation from local to global coordinates.

Get the transformation that brings the origin of the global reference frame to the origin of this frame (both in global coordinates).
