This interface is equivalent to the GM_OrientablePrimitive specified in ISO 19107. Orientable primitives are those that can be mirrored into new geometric objects in terms of their internal local coordinate systems (manifold charts).

For curves, the orientation reflects the direction in which the curve is traversed, that is, the sense of its parameterization. When used as boundary curves, the surface being bounded is to the "left" of the oriented curve.

For surfaces, the orientation reflects from which direction the local coordinate system can be viewed as right handed, the "top" or the surface being the direction of a completing z-axis that would form a right-handed system.

When used as a boundary surface, the bounded solid is "below" the surface. The orientation of points and solids has no immediate geometric interpretation in 3-dimensional space.

OrientablePrimitive objects are essentially references to geometric primitives that carry an "orientation" reversal flag (either "+" or "-") that determines whether this primitive agrees or disagrees with the orientation of the referenced object.
