Interface OrientableSurface

All Superinterfaces:

GeometricPrimitive, Geometry, GMLObject, Surface

All Known Implementing Classes:

DefaultOrientableSurface

public interface OrientableSurface
extends Surface

An OrientableSurface consists of a wrapped base Surface and an additional orientation.

If the orientation is *not* reversed, then the OrientableSurfacec is identical to the base curve. If the orientation is reversed, then the OrientableSurface is a reference to a surface with an up-normal that reverses the direction for this OrientableSurface, the sense of "the top of the surface".
