Class PgGeometry

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, PsUpdateIf, PgGeometryIf
    Direct Known Subclasses:
    PgAxes, PgJvxSrc, PgPointSet, PgSurfacePair, PgVectorField, PsKeyframe

    public abstract class PgGeometry
extends PsObject
implements PgGeometryIf
    Abstract class for all geometry classes in JavaView, and implementation of PgGeometryIf. Users may derive their own geometry classes either from this class resp. its subclasses, or by writing a class implementing the interface PgGeometryIf. Either of the two options is required to view the geometry in a JavaView display.

      • isEnabledInstanceSharing

        public boolean isEnabledInstanceSharing()
        Determines if sharing of vertices and other instances with a base geometry is enabled when this instance is filled in PgGeomtry#getJvx().
        Since:
        JavaView 3.84.012

        public void setEnabledInstanceSharing(boolean flag)
        Determines if sharing of vertices and other instances with a base geometry is enabled when this instance is filled in PgGeomtry#getJvx().

      • update

        public boolean update(java.lang.Object event)
        Update method of geometry updates registered panels, update listeners, and invokes a repaint in the registered displays.

        Usage:

        1. 1. event == this : geometry has changed, all panels will be updated.
        2. 2. event == null : geometry has changed, no need to update a panel.
        3. 3. event == a panel : geometry has changed, all panels except 'panel' will be updated.
        4. 4. event == else : unhandled event, error.
        Panels are not updated if they have not been created yet, or if they are not visible.

        Any update is forwarded to the parent of the geometry with the geometry as event.

        Any update is forwarded to each registered display with the geometry as event which leads to a repaint of the display.

        Specified by:
        update in interface PsUpdateIf
        Overrides:
        update in class PsObject

                                 int font)
        Set offset vector in pixel coordinates of label w.r.t. base point. The base point of vertices is the vertex, the base point of elements and edges and polygon edges is the barycenter, i.e. midpoint.

        First two components of attr are pixel coordinates determining the offset with respect to the base point. For example, an offset pair (1,-2) locates label center 1 to the right and 2 pixels up of the base point (since the upper left corner of the display is (0,0) in screen coordinates).

        Third component of attr is PgGeometryIf.LABEL_HEAD or PgGeometryIf.LABEL_CENTER or PgGeometryIf.LABEL_TAIL and indicates whether head, tail, or center of label is located at base+offset.

        Fourth component of attr is PgGeometryIf.LABEL_TOP or PgGeometryIf.LABEL_MIDDLE or PgGeometryIf.LABEL_BASE and indicates whether top, middle, or base of label is located at base+offset. Not implemented yet.

        Fifth component of attr indicates font. For possible fonts see PsConfig.

        Note, it is currently not possible to set the label attribute, say, of a single vertex unless you have a geometry with just one vertex.

        There exist one vector for each of the basic primitive types GEOM_ITEM_POINT, GEOM_ITEM_EDGE,GEOM_ITEM_POLYGON,GEOM_ITEM_ELEMENT,GEOM_ITEM_TETRA, GEOM_ITEM_NAME and GEOM_ITEM_TITLE. For possible type see PvGeometryIf#GEOM_ITEM_POINT and other items.

        Parameters:
        type - Type of geometry items affected by this setting
        xOffset - Offset in x-direction in pixels.
        yOffset - Offset in y-direction in pixels.
        horAdjust - Layout in horizontal direction, see PgGeometryIf#LABEL_.
        verAdjust - Layout in vertical direction, see PgGeometryIf#LABEL_.
        font - Identifier of font, see PsConfig#FONT_
        Returns:
        false if type is unknown.

      • getCenterOfElement

        public static PdVector getCenterOfElement(PdVector center,
                                          PdVector[] vertex,
                                          int[] vertInd)
        Compute the barycenter of a geometry element like face or polygon edge.
        Parameters:
        center - existing vector of dimension m_dim which will be filled and returned
        vertex - vertex array to which the index vector refers
        vertInd - index vector with indices in the vertex array
        Returns:
        Argument center is filled with the position of the barycenter

      • reflect

        public PgGeometry reflect(PdMatrix mat,
                          boolean bOrient,
                          boolean bVector)
        Generate a cloned geometry and transform vertices by a matrix. For example, this method is called to calculate mirror images of a geometry. Orientation of geometry affects surface vectors.
        Specified by:
        reflect in interface PgGeometryIf
        Parameters:
        mat - 3*3 or 4*4 transformation matrix
        bOrient - flag whether to keep the orientation of the geometry
        bVector - flag whether to keep the orientation of vectors
        Returns:
        new reflected copy of the geometry
        Author:

        Version:
        12.12.00, 1.10 revised (kp) Additional argument added for orientation of vectors.
