Detailed Description

An unified interface for defining and manipulating 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.

See Also: Joint

Constructor & Destructor Documentation

IMP::kinematics::KinematicForest::KinematicForest	(	kernel::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 67 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 92 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 177 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 168 of file KinematicForest.h.

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

sets the corodinates 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 189 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 external and internal coordinates when queried through the KinematicForest

Parameters

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