// CLASS DESCRIPTION (MFnGeometryData)
|
|
//
|
|
// This class is the function set for geometry data.
|
|
//
|
|
// Geometry data adds matrix and grouping (set) information to regular data
|
|
// and is used to pass geometry types such as mesh, lattice, and NURBS shape
|
|
// data through DG connections.
|
|
//
|
|
// User defined geometry data types (MPxGeometryData) are also supported
|
|
// by this class.
|
|
//
|
|
// The matrix within geometry data is the matrix used to convert the object
|
|
// into local space.
|
