List of all members.


Detailed Description

Unrestricted motion for a rigid body (six mobilities).

Orientation is modeled the same as for the Orientation mobilizer, that is, using quaternions to avoid singularities. A modeling option exists to have the joint modeled with a 1-2-3 body fixed Euler sequence like a Gimbal mobilizer. Translational generalized coordinates are x,y,z translations along the F (inboard) axes.

Member Function Documentation

Free& addBodyDecoration ( const Transform X_BD,
const DecorativeGeometry g 
) [inline]

Add decorative geometry specified relative to the new (outboard) body's reference frame B, or to the outboard mobilizer frame M attached to body B, or to the inboard mobilizer frame F attached to the parent body P.

Note that the body itself may already have had some decorative geometry on it when it was first put into this MobilizedBody; in that case this just adds more.

Reimplemented from MobilizedBody.

References MobilizedBody::addBodyDecoration().

Free& addOutboardDecoration ( const Transform X_MD,
const DecorativeGeometry  
) [inline]

Add decorative geometry specified relative to the outboard mobilizer frame M attached to body B.

If body B already has decorative geometry on it, this just adds some more.

Reimplemented from MobilizedBody.

References MobilizedBody::addOutboardDecoration().

Free& addInboardDecoration ( const Transform X_FD,
const DecorativeGeometry  
) [inline]

Add decorative geometry specified relative to the inboard mobilizer frame F attached to the parent body P.

If body P already has decorative geometry on it, this just adds some more.

Reimplemented from MobilizedBody.

References MobilizedBody::addInboardDecoration().

Free& setDefaultInboardFrame ( const Transform X_PF  )  [inline]

Change this mobilizer's frame F on the parent body P.

Calling this method invalidates the MobilizedBody's topology, so the containing matter subsystem's realizeTopology() method must be called again. A reference to this MobilizedBody is returned so that this can be chained like an assignment operator.

Reimplemented from MobilizedBody.

References MobilizedBody::setDefaultInboardFrame().

Free& setDefaultOutboardFrame ( const Transform X_BM  )  [inline]

Change this mobilizer's frame M fixed on this (the outboard) body B.

Calling this method invalidates the MobilizedBody's topology, so the containing matter subsystem's realizeTopology() method must be called again. A reference to this MobilizedBody is returned so that this can be chained like an assignment operator.
