public interface Surface
extends OrientableSurface

This interface is equivalent to the GM_Surface specified in ISO 19107. Surface is a subclass of Primitive and is the basis for 2-dimensional geometry. Unorientable surfaces such as the M�bius band are not allowed.

The orientation of a surface chooses an "up" direction through the choice of the upward normal, which, if the surface is not a cycle, is the side of the surface from which the exterior boundary appears counterclockwise. Reversal of the surface orientation reverses the curve orientation of each boundary component, and interchanges the conceptual "up" and "down" direction of the surface.

If the surface is the boundary of a solid, the "up" direction is usually outward. For closed surfaces, which have no boundary, the up direction is that of the surface patches, which must be consistent with one another.
