 The ellipsoid is placed on the mobilizer's inboard frame F, with half-axis dimensions along F's x,y,z respectively.
 Ellipsoid (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.

Detailed Description

Three mobilities -- coordinated rotation and translation along the surface of an ellipsoid fixed to the parent (inboard) body.

The generalized coordinates are the same as for a Ball (Orientation) joint, that is, a quaternion or 1-2-3 Euler sequence.


Constructor & Destructor Documentation

Ellipsoid ( Direction  = Forward  )  [explicit]

The ellipsoid is placed on the mobilizer's inboard frame F, with half-axis dimensions along F's x,y,z respectively.

Ellipsoid ( 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.

Ellipsoid ( 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.

Ellipsoid ( MobilizedBody parent,
const Transform inbFrame,
const Body ,
const Transform outbFrame,
const Vec3 radii,
Direction  = Forward 
)

Use this constructor to specify mobilizer frames which are not coincident with the body frames, and give the radii at the same time.


Member Function Documentation

Ellipsoid& 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().

Ellipsoid& 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().

Ellipsoid& 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.

Ellipsoid& 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().

Ellipsoid& 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.
