Constructor & Destructor Documentation

IMP::kinematics::DihedralAngleRevoluteJoint::DihedralAngleRevoluteJoint ( IMP::core::RigidBody  parent,
IMP::core::RigidBody  child,
IMP::core::XYZ  a,
IMP::core::XYZ  b,
IMP::core::XYZ  c,
IMP::core::XYZ  d 

constructs a dihedral angle that revolves around the axis b-c, using a,b,c,d as witnesses for the dihedral angle

parent,childkinematic nodes upstream and downstream (resp.) of this joint
a,b,c,d'witnesses' whose coordinates define the dihedral angle between the planes containing a-b-c and b-c-d)
It is assumed that neither a, b and c are downstream of child, and also that d is not upstream of it

Member Function Documentation

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

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

Implements IMP::kinematics::RevoluteJoint.

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

updates the rot_axis_unit_vector_ and rot_axis_origin_ variables in parent coordinates based on the witnesses b_ and c_, using b_-c_ as the axis of rotation

it is assumed b_ and c_ have update Cartesian coordinates

Implements IMP::kinematics::RevoluteJoint.
