IDLgrPolygon

Superclasses | Creation | Properties | Methods | Version History

A polygon object represents one or more polygons that share a given set of vertices and rendering attributes. All polygons must be convex—that is, a line connecting any pair of vertices on the polygon cannot fall outside the polygon. Concave polygons can be converted to a set of convex polygons using the IDLgrTessellator object.

An IDLgrPolygon object is an atomic graphic object; it is one of the basic drawable elements of the IDL Object Graphics system, and it is not a container for other objects.
