Detailed Description

Geometry data function set.

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.
