Constructor & Destructor Documentation

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

Create a prismatic joint whose axis of translation is from a to b, which serve as witnesses for the joint transformation (a is associated with the parent and b with the child)

IMP::kinematics::PrismaticJoint::PrismaticJoint	(	IMP::core::RigidBody	parent,
		IMP::core::RigidBody	child
	)

Create a prismatic joint whose axis of translation is between the reference frames of parent and child, who also serve as witnesses for the joint transformation

Member Function Documentation

double IMP::kinematics::PrismaticJoint::get_length ( ) const

Get the length of the prismatic joint.

The length is defined as the length between the two witnesses.

void IMP::kinematics::PrismaticJoint::set_length ( double l )

sets the length of the prismatic joint to l, that is the length between the two witnesses set up upon construction (in a lazy fashion, without updating external coords). Updates the owner of the change in internal coordinates.

Note: it is assumed that l > 0, and for efficiency, runtime checks for this are not made in fast mode

virtual void IMP::kinematics::PrismaticJoint::update_joint_from_cartesian_witnesses ( )

protectedvirtual

Update the length and transformation of the prismatic joint based on the distance and relative orientation of the witnesses given upon construction.

Note: It is assumed that external coordinates are updated before calling this function.

Reimplemented from IMP::kinematics::Joint.
