    • Constructor Detail

      • PgGraph

        public PgGraph(int dim)
        Deprecated. since 2004, use PgGraph() instead since only dim=3 is supplied.
        Create a graph of a scalar-valued function over a rectangular 2D domain. The resulting graph surface lives in 2+1=3-dimensional space.

      • PgGraph

        public PgGraph()
        Create a graph of a scalar-valued function over a rectangular 2D domain. The resulting graph surface lives in 2+1=3-dimensional space.

    • Method Detail

      • init

        public void init()
        Initialize sliders.
        Overrides:
        init in class PgElementSet

      • clone

        public java.lang.Object clone()
        Duplicate geometry by recursively cloning all instance variables except inspector panels and lists of registered listeners. The parent relationship is maintained only within this class but not to external classes.
        Specified by:
        clone in interface PgGeometryIf
        Overrides:
        clone in class PgElementSet
        See Also:
        copy(PsObject)
        Version:
        16.01.04, 1.00 created (kp)

      • copy

        public void copy(PsObject object)
        Copy a geometry into this geometry.

        The argument was changed from PgGeometry to PsObject since there were problems in J/Link which preferred to use PsObject#copy(PsObject) instead of PgGeometry#copy(PsObject).

        Overrides:
        copy in class PgElementSet
        See Also:
        PgElementSet.clone()
        Version:
        16.01.04, 1.20 revised (kp) Copy all major instance variables instead of linking them.
        08.11.02, 1.10 revised (kp) Argument changed to PsObject from PgGeometry.

      • toString

        public java.lang.String toString()
        Create a multi-line string representation with detailed information about all instance variables.
        Specified by:

      • setNumVertices

        public void setNumVertices(int num)
        Get domain of graph.
        Overrides:
        setNumVertices in class PgPointSet

      • getDomain

        public PgDomain getDomain()
        Get domain of graph.

      • getSurface

        public PgElementSet getSurface()

      • setSurfaces

        public void setSurfaces(PgDomain domain,
                        PgElementSet surface)
        Assign a domain and image surface which provide the data for this graph. The sum of domain and surface dimensions must be equal to the dimension of this graph surface.

        Number of vertices of domain and surface must be equal. The number of vertices and the mesh connectivity of this graph are both adjusted to the properties of the domain.

        This graph is registered as update listener of the new arguments, see addUpdateListener.

        Version:
        17.01.04, 1.10 revised (kp) Register as updateListener instead of parent.

      • getFunction

        public PuFunction getFunction()
        Get function object of the graph.

      • setFunction

        public boolean setFunction(PuFunction function)
        Set function object of the graph whose number of functions must be equal to the dimension of the surface component of the graph, i.e. equal to the dimension of vertices of the graph minus the domain.

        This graph is registered as update listener of the new function, see addUpdateListener.

        Version:
        01.08.04, 1.20 revised (kp) No longer invoke update(), must be called externally.
        17.01.04, 1.10 revised (kp) Register as updateListener instead of parent.
