Documentation

Create and manipulate Subdiv Surface dependency node data
Description

MFnSubdData allows the creation and manipulation of Subdivision Surface data objects for use in the dependency graph.

If a user written dependency node either accepts or produces Subdivision Surfaces, 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 kSubdiv when data of this type is present.

If a node is receiving a Subdivision Surface via an input attribute, the asSubdSurface method of MDataHandle can be used to access that input Subdivision Surface.

If a node is to create a Subdivision Surface and send it via an output attribute, a new MFnSubdData must be instantiated and then the create method called to build the actual data block as an MObject. This MObject should be passed to the MFnSubd::create method as the parentOrOwner parameter so that the Subdivision Surface will be constructed inside the data block. The MDataHandle::set routine is then used to pass the data block down the connection.

Functions

MFnSubdData:: MFnSubdData ()

Description

Default class constructor. The function set is not attached to an MObject.

MFnSubdData:: MFnSubdData ( MObject & object, MStatus * ReturnStatus )

Description

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

Arguments

  • object the MObject to attach the function set to
  • ReturnStatus the return status
    • 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

MFnSubdData:: MFnSubdData ( const MObject & object, MStatus * ReturnStatus )

Description

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

Arguments

  • object the const MObject to attach the function set to
  • ReturnStatus the return status
    • 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

MFnSubdData:: ~MFnSubdData ()

Description

The class destructor.

MFn::Type MFnSubdData:: type () const

Description

Return the type of this function set.

Return Value

  • the constant MFn::kSubdivData

MObject MFnSubdData:: create ( MStatus * ReturnStatus )

Description

Create a new MObject, attach it to this instance and initialize it with a data block capable of holding a Subdivision Surface.

Arguments

  • ReturnStatus kSuccess

Return Value

  • the new MObject

This class has no child classes.
