Constructor Summary

DirectManipulationRendererJ3D()
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, YAxis or ZAxis
