Class Plot3DState

  • Direct Known Subclasses:
    SphericalPlotState
    public class Plot3DState
extends PlotState
    PlotState subclass which has specific features for specifying the state of 3D scatter plots. The most important extra feature is the rotation matrix, which describes the viewing angle for the 3D data space.

        public Plot3DState()

    • Method Detail

      • setRotation

        public void setRotation​(double[] matrix)
        Sets the rotation matrix.
        Parameters:
        matrix - 9-element 3d rotation matrix

      • getRotation

        public double[] getRotation()
        Returns the rotation matrix.
        Returns:
        9-element 3d rotation matrix

      • setFogginess

        public void setFogginess​(double fog)
        Sets the intensity of fog used for depth rendering (1 is a reasonable amount; 0 is no fog).
        Parameters:
        fog - fog intensity

      • getFogginess

        public double getFogginess()
        Returns the intensity of fog used for depth rendering.
        Returns:
        fog intensity

      • setRotating

        public void setRotating​(boolean isRotating)
        Sets whether the plot is currently rotating. A true value for this indicates that the whole set of data points does not need to be drawn; a sequence of plot requests with isRotating true must be followed quickly by one with isRotating false.
        Parameters:
        isRotating - true iff this plot is currently in the middle of a sequence of rotation operations

      • getRotating

        public boolean getRotating()
        Indicates whether the plot is currently rotating. A true value for indicates that the whole set of data points does not need to be drawn; a sequence of plot requests with isRotating true must be followed quickly by one with isRotating false.
        Returns:
        true if not all the points need to be drawn this time

      • setZoomScale

        public void setZoomScale​(double zoomScale)
        Returns the zoom level. Unity is normal size, and a larger number means more magnification.
        Parameters:
        zoomScale - zoom level

      • getZoomScale

        public double getZoomScale()
        Sets the zoom level.
        Returns:
        zoom level

      • equals

        public boolean equals​(java.lang.Object otherObject)
        Overrides:
        equals in class PlotState
