      • setModel

        void setModel​(Model model)
        Specifies the scene controller's model. This method fires an AVKey.MODEL property change event.
        Parameters:
        model - the scene controller's model.

      • getView

        View getView()
        Returns the current view. This method fires an AVKey.VIEW property change event.

        the current view.

      • setView

        void setView​(View view)
        Sets the current view.
        Parameters:
        view - the view.

      • repaint

        int repaint()
        Cause the window to regenerate the frame, including pick resolution.
        Returns:
        if greater than zero, the window should be automatically repainted again at the indicated number of milliseconds from this method's return.

      • setVerticalExaggeration

        void setVerticalExaggeration​(double verticalExaggeration)
        Specifies the exaggeration to apply to elevation values of terrain and other displayed items.

        the current vertical exaggeration.

      • getPickedObjectList

        PickedObjectList getPickedObjectList()
        Returns the list of picked objects at the current pick point. The returned list is computed during the most recent call to repaint.
        Returns:
        the list of picked objects at the pick point, or null if no objects are currently picked.

      • getObjectsInPickRectangle

        PickedObjectList getObjectsInPickRectangle()
        Returns the list of picked objects that intersect the current pick rectangle. The returned list is computed during the most recent call to repaint.

      • getFramesPerSecond

        double getFramesPerSecond()
        Returns the current average frames drawn per second. A frame is one repaint of the window and includes a pick pass and a render pass.

        the current average number of frames drawn per second.

      • getFrameTime

        double getFrameTime()
        Returns the per-frame timestamp.
        Returns:

      • setPickPoint

        void setPickPoint​(java.awt.Point pickPoint)
        Specifies the current pick point in AWT screen coordinates, or null to indicate that there is no pick point. Each frame, this scene controller determines which objects are drawn at the pick point and places them in a PickedObjectList. This list can be accessed by calling getPickedObjectList().

        If the pick point is null, this scene controller ignores the pick point and the list of objects returned by getPickedObjectList is empty.

        Parameters:
        pickPoint - the current pick point, or null.

      • getPickPoint

        java.awt.Point getPickPoint()
        Returns the current pick point in AWT screen coordinates.
        Returns:
        the current pick point, or null if no pick point is current.
        See Also:
        setPickPoint(java.awt.Point)

      • setPickRectangle

        void setPickRectangle​(java.awt.Rectangle pickRect)
        Specifies the current pick rectangle in AWT screen coordinates, or null to indicate that there is no pick rectangle. Each frame, this scene controller determines which objects intersect the pick rectangle and places them in a PickedObjectList. This list can be accessed by calling getObjectsInPickRectangle().

        If the pick rectangle is null, this scene controller ignores the pick rectangle and the list of objects returned by getObjectsInPickRectangle is empty.

        Parameters:
        pickRect - the current pick rectangle, or null.

      • getPickRectangle

        java.awt.Rectangle getPickRectangle()
        Returns the current pick rectangle in AWT screen coordinates.
