simscape.multibody.Ellipsoid Class

Namespace: simscape.multibody
Superclasses: simscape.multibody.Geometry

Create ellipsoidal geometry

Since R2022a

Description

Use an object of the simscape.multibody.Ellipsoid class to represent ellipsoidal geometry. The reference frame of the geometry is located at the centroid of the ellipsoid and the semi-axes are aligned with the axes of the reference frame. To specify the dimensions of the geometry, use the Radii property.

Creation

Description

ellipsoid = simscape.multibody.ellipsoid creates an ellipsoidal geometry with default values.

ellipsoid = simscape.multibody.ellipsoid(radii) creates an ellipsoidal geometry with the specified radii.

`Radii` — Lengths of three semi-axes of ellipsoid
`simscape.Value([1 1 2],"m")` (default) | `simscape.Value([x y z],"Length unit")` | `simscape.Value([x y z]',"Length unit")`

Lengths of the three semi-axes of the ellipsoidal geometry, specified as a simscape.Value object that represents a 3-by-1 or 1-by-3 array with a unit of length. The array defines the intercepts of the ellipsoidal surface with the axes of the reference frame.
