Constructor and Description
Irregular3DSet(MathType type, float[][] samples) a 3-D irregular set with null errors, CoordinateSystem and Units are defaults from type; topology is computed by the constructor
Irregular3DSet(MathType type, float[][] samples, CoordinateSystem coord_sys, Unit[] units, ErrorEstimate[] errors, Delaunay delan) a 3-D irregular set; samples array is organized float[3][number_of_samples]; no geometric constraint on samples; if delan is non-null it defines the topology of samples (which may have manifold dimension 2 or 3), else the constructor computes a topology with manifold dimension 3; note that Gridded3DSet can be used for an irregular set with domain dimension 3 and manifold dimension 1; coordinate_system and units must be compatible with defaults for type, or may be null; errors may be null
