IDL Reference Guide: Graphics Object Classes

IDLgrSurface

A surface object represents a shaded or vector representation of a mesh grid.

An IDLgrSurface 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.

Superclasses
