// CLASS DESCRIPTION (MFnLatticeDeformer)
|
|
//
|
|
// MFnLatticeDeformer is the function set for lattice deformers. Lattice
|
|
// deformers use FFDs to deform geometry.
|
|
//
|
|
// The lattice deformer is actually a small network of dependency nodes in
|
|
// the dependency graph. This function set is provided to make
|
|
// manipulation of the network easier. The main deformer node should be
|
|
// given to this function set as its object.
|
|
//
|
|
// There are two lattices associated with a lattice deformer. There is a
|
|
// base lattice that defines the start position for the lattice. The
|
|
// second lattice is the version that is modified to deform the geometry.
|
|
// The difference between the two lattices defines the deformation that is
|
|
// applied to the geometry.
|
|
//
|
|
// The base lattice is a very simple shape that only defines a box in
|
|
// space. The base lattice should be modified by using the standard DAG
|
|
// transformation support. The second deformable lattice has geometry
|
|
// that can be modified using the MFnLattice function set.
|
|
//
|
|
// For a piece of geometry to be modified by this deformer, the geometry
|
|
// must be attached to the deformer (use addGeometry method) and the
|
|
// geometry must be contained within the base lattice. The resetLattice
|
|
// method can be used to make the lattice resize to the bounding box of
|
|
// the attached geometry.
|
|
