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.

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] xDiv Lattice divisions in x (must be at least 2). [in] yDiv Lattice divisions in y (must be at least 2). [in] zDiv Lattice divisions in z (must be at least 2). [in] parentOrOwner Parent node or data wrapper. See discussion above. [out] ReturnStatus Status 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.
