public class CurveDrawer
extends LineDrawing

Provides support for a Displayable that comprises a set of drawn curves. The curves can be drawn in in spherical and other non-Cartesian coordinate systems by selecting the appropriate RealTypes or RealTupleType.

Sample usage:

  CurveDrawer curveDraw =
      new CurveDrawer(RealType.Latitude, RealType.Longitude);
  curveDraw.addAction(new ActionImpl() {
      public void doAction()
          throws VisADException, RemoteException
      {
          UnionSet curves = curveDraw.getData();
          (do something useful with the curves)
      }
  });
