public class DirectManipulationRendererJ2D
extends RendererJ2D

DirectManipulationRendererJ2D is the VisAD class for direct manipulation rendering under Java2D.

This DataRenderer supports direct manipulation for Real, RealTuple and Field Data objects (Field data objects must have RealType or RealTupleType ranges and Gridded1DSet domain Sets); no RealType may be mapped to multiple spatial DisplayRealTypes; the RealType of a Real object must be mapped to XAxis, YAxis or YAxis; at least one of the RealType components of a RealTuple object must be mapped to XAxis, YAxis or YAxis; the domain RealType and at least one RealType range component of a Field object must be mapped to XAxis or YAxis
