Detailed Description
Three translational mobilities.The generalized coordinates are x,y,z translations along the parent (inboard) F frame axes.

| Translation (MobilizedBody &parent, const Body &) | |
| By default the parent body frame and the body's own frame are used as the inboard and outboard mobilizer frames, resp. | |

| Translation & | addBodyDecoration (const Transform &X_BD, const DecorativeGeometry &g) |
| 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. | |

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

Member Function Documentation
| Translation& 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().
| Translation& 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().
| Translation& 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().
| Translation& 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().
| Translation& 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.

| Translation& setDefaultTranslation | ( | const Vec3 & | p_FM | ) | [inline] |
| const Vec3& getDefaultTranslation | ( | ) | const [inline] |
At stage Velocity or higher, return the cross-mobilizer velocity V_FM, the relative velocity of this body's "moving" mobilizer frame M in the parent body's corresponding "fixed" frame F, measured and expressed in F.
Note that this isn't the usual spatial velocity since it isn't expressed in G.
