Detailed Description

Swept Geometry function set for dependency node data.

MFnDynSweptGeometryData provides access to the MDynSweptLine and MDynSweptTriangle data for use in a user defined dependency graph node. The data is provided as an output from the geoConnector node and is primarily used to determine positional information over time.

If a user written dependency node accepts MFnDynSweptGeometryData, then this class is used to extract data that comes from the geoConnector node. The MDataHandle::type method will return kDynSweptGeometry 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 MFnDynSweptGeometryData.

Important note: Users can create the data for connections but cannot produce the contents of the data as this is reserved for the Maya Dynamics internals.

Examples:
simpleFluidEmitter/simpleFluidEmitter.cpp, and sweptEmitter/sweptEmitter.cpp.

Constructor & Destructor Documentation

MFnDynSweptGeometryData ( MObject object,
MStatus ReturnStatus = NULL 
)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters
[in]objectThe MObject to attach the function set to
[out]ReturnStatusthe return status
Status Codes:
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject
MFnDynSweptGeometryData ( const MObject object,
MStatus ReturnStatus = NULL 
)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters
[in]objectThe MObject to attach the function set to
[out]ReturnStatusthe return status
Status Codes:
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

Member Function Documentation
