// CLASS DESCRIPTION (MItMeshFaceVertex)
|
|
//
|
|
// This class is the iterator for polygonal surfaces - iterates over
|
|
// face vertices.
|
|
//
|
|
// The iterator functions in two modes depending on whether a component
|
|
// is specified. When a component is not given or is NULL the iteration
|
|
// will be over all polygons for the surface. When a component is given
|
|
// this iterator will iterate over the polygons specified in the component.
|
|
// When iterating over components a DAG path to the surface must also be
|
|
// supplied.
|
|
