MFnLatticeData Class Reference

#include <MFnLatticeData.h>

Class 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.

Member Function Documentation

MFn::Type type ( ) const
virtual

Function set type.

Return the class type : MFn::kLatticeData.

Reimplemented from MFnGeometryData.

const char * className ( ) const
protectedvirtual

Class name.

Return the class name : "MFnLatticeData".

Reimplemented from MFnGeometryData.

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]ReturnStatusreturn status
Returns
A handle to the new lattice data object
Status Codes:
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]ReturnStatusreturn status
Returns
A handle to the new lattice data object
