PlaneAltitudeEvaluator Interface
Plane Evaluation methods.
- These provide the necessary queries to implement clipping operations without knowing if the plane in use is a ClipPlane, Plane3dByOriginAndUnitNormal, Plane3dByOriginAndVectors, Point4d.
- The Plane3d class declares obligation to implement these methods, and passes the obligation on to concrete implementations by declaring them as abstract members which the particular classes can implement.
- It is intended that this interface be deprecated because its implementation by Plane3d provides all of its functionality and allows more to be added.
