// CLASS DESCRIPTION (MItMeshPolygon)
|
||||
//
|
||||
// This class is the iterator for polygonal surfaces.
|
||||
//
|
||||
// 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.

||||
