Detailed Description

Lattice Data dependency graph type.

This simple function set is used to create lattice data objects that can be transmitted through the dependency graph. It can also be used to extract the lattice geometry from the data object.

See MDataHandle and MDataBlock for more information about getting and setting data in the dependency graph.

Examples:: latticeNoise/latticeNoiseNode.cpp.

Constructor & Destructor Documentation

MFnLatticeData	(	MObject &	object,
		MStatus *	ReturnStatus = `NULL`
	)

Constructor.

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

Parameters

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the 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

MFnLatticeData	(	const MObject &	object,
		MStatus *	ReturnStatus = `NULL`
	)

Constructor.

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

Parameters

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the 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

MFn::Type type ( ) const

virtual

Function set type.

Return the class type : MFn::kLatticeData.

Returns: the class type.

Reimplemented from MFnGeometryData.

OPENMAYA_MAJOR_NAMESPACE_OPEN const char * className ( )

static

Returns the name of this class.

Return the class name : "MFnLatticeData".

Returns: Name of this class.

MObject create ( MStatus * ReturnStatus = NULL )

This method create a new lattice data object for use with the dependency graph.

A node's lattice attribute may be set with this object using MDataHandle.

Parameters

[out] ReturnStatus return status

Returns: A handle to the new lattice data object

Status Codes:

MS::kSuccess operation successful
MS::kInsufficientMemory out of memory

MObject lattice ( MStatus * ReturnStatus = NULL )

Returns the lattice geometry so that it may be modified using the MFnLattice function set.

It is possible that the data object will be NULL, indicating that the data handle (MDataHandle) or plug (MPlug) that owns this data has not initialized it. In this case, the create method of this function set can be used to create a new data object that can be used to set the data handle or plug.

Parameters

[out] ReturnStatus return status

Returns: A handle to the new lattice data object

Status Codes:

MS::kSuccess operation successful
MS::kFailure function set does not have valid object
