MobilizedBody::Gimbal Class Reference
#include <MobilizedBody.h>
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.

Member Function Documentation
| 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 MobilizedBody.
References MobilizedBody::addBodyDecoration().
| 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 MobilizedBody.
References MobilizedBody::addOutboardDecoration().
| 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 MobilizedBody.
References MobilizedBody::addInboardDecoration().
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().
Change this mobilizer's frame M fixed on this (the outboard) body B.
