MFnLattice Class Reference

#include <MFnLattice.h>

Class Description

Lattice function set.

MFnLattice is the function set for lattice shapes and lattice geometry. It can be used on lattices in the DAG or on lattice geometry from a dependency node attribute.

Lattices are most commonly used for specifying FFDs (free-form deformations). See MFnLatticeDeformer for more information on those.

MFnLatticeData can be used to create new lattice data objects for use with dependency node attributes.

Member Function Documentation

MFn::Type type ( ) const
virtual

Function set type.

Return the class type : MFn::kLattice.

Reimplemented from MFnDagNode.

OPENMAYA_MAJOR_NAMESPACE_OPEN const char * className ( ) const
protectedvirtual

Class name.

Return the class name : "MFnLattice".

Reimplemented from MFnDagNode.

MObject create ( unsigned int  xDiv,
unsigned int  yDiv,
unsigned int  zDiv,
MObject  parentOrOwner = MObject::kNullObj,
MStatus ReturnStatus = NULL 
)

Create a new lattice.

This can be used to create either a new lattice shape in the DAG, or to place new lattice geometry into a dependency graph lattice data object. Lattice data objects can be created with MFnLatticeData or can be obtained from an MDataHandle in the compute method of a dependency node.

The parentOrOwner argument is used to specify the owner of the new lattice.

If parentOrOwner is a kLatticeData data wrapper (e.g. as returned by MFnLatticeData::create) then a new kLattice object will be created and placed inside the wrapper. No nodes will be created and the method will return the kLattice object.

If parentOrOwner is NULL then new lattice and transform nodes will be created and added to the DAG, with the lattice parented under the transform. The method will return the transform node.

If parentOrOwner is a DAG node then a new lattice node will be created and parented under that DAG node. The method will return the lattice node.

Parameters
[in]xDivLattice divisions in x (must be at least 2).
[in]yDivLattice divisions in y (must be at least 2).
[in]zDivLattice divisions in z (must be at least 2).
[in]parentOrOwnerParent node or data wrapper. See discussion above.
[out]ReturnStatusStatus code.
Returns
A handle to the new lattice data, lattice node or transform node. See the discussion of the parentOrOwner parameter above for more details.
Status Codes:
  • MS::kSuccess Operation successful.
  • MS::kFailure Unexpected failure.
  • MS::kInsufficientMemory Out of memory.
  • MS::kLicenseFailure Application not licensed for attempted operation.
MStatus reset ( double  sSize = 1.0,
