Detailed Description

Sphere function set for dependency node data .

MFnSphereData allows the creation and manipulation of sphere (represented as MObjects) data objects for use in the dependency graph.

If a user written dependency node either accepts or produces MObjects containing spheres, then this class is used to extract or create the data that comes from or goes to other dependency graph nodes. The MDataHandle::type method will return kSphere when data of this type is present. To access it, the MDataHandle::data method is used to get an MObject for the data and this should then be used to initialize an instance of MFnNurbsSurface.

The new MObject

double MFnSphereData::radius ( MStatus ReturnStatus = NULL  )  const

Return the radius of the sphere attached to this instance.

Parameters:
[out]  ReturnStatus  kSuccess if the instance has a sphere attached to it, and kFailure otherwise.
Returns:
The radius

MStatus MFnSphereData::setRadius ( double  rad  ) 

Change the radius of the sphere attached to this instance instance as an MObject.

Parameters:
[in]  rad  the new radius
Returns:
kSuccess if the instance has a sphere attached to it, and kFailure otherwise.
