Detailed Description

Define and manipulate a kinematic structure over a model.

The kinematic structure is defined as a forest over model particles at a certain hierarchy, such that a directed edge indicates the propagation of changes in internal coordinates (joint values) to values of external (Cartesian) coordinates.

Constructor & Destructor Documentation

IMP::kinematics::KinematicForest::KinematicForest	(	Model *	m,
		IMP::atom::Hierarchy	hierarchy
	)

Builds a kinematic forest automatically from a hierarchy that contains rigid bodies and adds a ScoreState to the model, to make sure the internal and external coordinates are synced before model updating

Member Function Documentation

Joint* IMP::kinematics::KinematicForest::add_edge	(	IMP::core::RigidBody	parent,
		IMP::core::RigidBody	child
	)

Adds a kinematic edge between parent and child, using a TransformationJoint between them, and decorating them as KinematicNodes if needed.

Definition at line 63 of file KinematicForest.h.

void IMP::kinematics::KinematicForest::add_edge ( Joint * joint )

Adds a kinematic edge between the joint parent and child rigid bodies, decorating them as KinematicNodes if needed. The joint becomes owned by this KinematicForest, such that changes to the joint are synchronized with the KinematicForest

Note: it is assumed that neither the joint or the rigid bodies in it were previously added to a kinematic forest (might change in future IMP versions)

void IMP::kinematics::KinematicForest::add_rigid_bodies_in_chain ( IMP::core::RigidBodies rbs )

adds edges between each pair of consecutive rigid bodies in the list rbs, using default TransformationJoint joints (transforming from one rigid body to the next)

Parameters

rbs	list of n consecutive rigid bodies

Definition at line 89 of file KinematicForest.h.

void IMP::kinematics::KinematicForest::apply_transform_safely ( IMP::algebra::Transformation3D tr )

apply a rigid body transformation to the entire forest safely

Apply a rigid body transformation to the entire forest safely, such that the forest will return correct external and internal coordinates if queries through get_coordinates_safe() or get_reference_frame_safe(), or after updating with update_all_external_coordinates() or update_all_internal_coordinates(), respectively.

Get information about the module and version of the object.

Reimplemented from IMP::Object.

Definition at line 43 of file KinematicForest.h.

void IMP::kinematics::KinematicForest::mark_external_coordinates_changed ( )

notifies the tree that external Cartesian coordinates have changed and therefore internal (joint) coordinates are not up to date

Definition at line 178 of file KinematicForest.h.

void IMP::kinematics::KinematicForest::mark_internal_coordinates_changed ( )

notifies the tree that joint (internal) coordinates have changed and therefore external coordinates are not up to date

Definition at line 169 of file KinematicForest.h.

void IMP::kinematics::KinematicForest::reset_root ( IMP::Particle * new_root )

rebuild tree (same topology but change directionality)

Definition at line 96 of file KinematicForest.h.

void IMP::kinematics::KinematicForest::set_coordinates_safe	(	IMP::core::RigidBody	rb,
		IMP::algebra::Vector3D	c
	)

sets the coordinates of a particle, and makes sure that particles and joints in the tree will return correct external and internal coordinates

Parameters

rb	a rigid body that was previously added to the tree
c	new coordinates

Definition at line 190 of file KinematicForest.h.

Here is the call graph for this function:

void IMP::kinematics::KinematicForest::set_reference_frame_safe	(	IMP::core::RigidBody	rb,
		IMP::algebra::ReferenceFrame3D	r
	)

sets the reference frame of a rigid body, and makes sure that particles and joints in the tree will return correct internal coordinates when queried directly through the KinematicForest

Parameters

rb	a rigid body that was previously added to the tree
r	new reference frame

Definition at line 238 of file KinematicForest.h.

Here is the call graph for this function:

void IMP::kinematics::KinematicForest::update_all_external_coordinates ( )

update all external coordinates of particles in the forest based on their internal coordinates

Definition at line 118 of file KinematicForest.h.

Here is the call graph for this function:

void IMP::kinematics::KinematicForest::update_all_internal_coordinates ( )

updated internal coordinates in the forest based on the current cartesian coordinates and the architechture of joints in the tree
