Detailed Description

Three mobilities -- unrestricted orientation modeled as a 1-2-3 body-fixed Euler angle sequence.

This is singular when the middle angle is 90 degrees.


Constructor & Destructor Documentation

SimTK::MobilizedBody::Gimbal::Gimbal ( MobilizedBody parent,
const Body ,
Direction  = Forward 
)

By default the parent body frame and the body's own frame are used as the inboard and outboard mobilizer frames, resp.

SimTK::MobilizedBody::Gimbal::Gimbal ( MobilizedBody parent,
const Transform inbFrame,
const Body ,
const Transform outbFrame,
Direction  = Forward 
)

Use this constructor to specify mobilizer frames which are not coincident with the body frames.


Member Function Documentation

Gimbal& SimTK::MobilizedBody::Gimbal::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 SimTK::MobilizedBody.

Gimbal& SimTK::MobilizedBody::Gimbal::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 SimTK::MobilizedBody.

Gimbal& SimTK::MobilizedBody::Gimbal::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 SimTK::MobilizedBody.

Gimbal& SimTK::MobilizedBody::Gimbal::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 SimTK::MobilizedBody.

Gimbal& SimTK::MobilizedBody::Gimbal::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.
