Constructor & Destructor Documentation

IMP::kinematics::BondAngleRevoluteJoint::BondAngleRevoluteJoint	(	IMP::core::RigidBody	parent,
		IMP::core::RigidBody	child,
		IMP::core::XYZ	a,
		IMP::core::XYZ	b,
		IMP::core::XYZ	c
	)

constructs a joint that controls the angle a-b-c. The joint revolves around the axis that passes through b, normal to the plane containing a, b and c. a,b and c are the witnesses for the bond angle.

Parameters

parent,child	kinematic nodes upstream and downstream (resp.) of this joint
a,b,c	'witnesses' whose coordinates define the joint angle a-b-c

Note: It is assumed that a and b are upstream of or inside this joint's child rigid body, and that c is downstream of it or inside it.

Member Function Documentation

virtual double IMP::kinematics::BondAngleRevoluteJoint::get_current_angle_from_cartesian_witnesses ( ) const

protectedvirtual

this protected method uses the Cartesian witnesses to compute the actual current bond angle of this joint (assuming external coordinates of required Cartesian witnesses are up to date)

Implements IMP::kinematics::RevoluteJoint.

virtual void IMP::kinematics::BondAngleRevoluteJoint::update_axis_of_rotation_from_cartesian_witnesses ( )

protectedvirtual

updates the rot_axis_unit_vector_ and rot_axis_origin_ variables using b_ as origin of rotation and a vector perpendicular to the plane containing a_,b_,c_ as axis of rotation, in global coordinates

Implements IMP::kinematics::RevoluteJoint.
