        Compute screen points required to draw a leader line on a tactical symbol. This method returns two points that will draw a line out from the center of the symbol.
        Parameters:
        dc - Current draw context.
        symbolPoint - Symbol position in model coordinates.
        heading - Direction of movement, as a bearing clockwise from North.
        length - Length of the indicator line, in pixels.
        Returns:
        List of screen points that describe the speed leader line.

      • computeGroundHeadingIndicatorPoints

        public static java.util.List<? extends java.awt.geom.Point2D> computeGroundHeadingIndicatorPoints​(DrawContext dc,
                                                                                                  Vec4 symbolPoint,

        Compute screen points required to draw a leader line on a tactical ground symbol. This method returns three points that will draw a line down from the base of the symbol and then out in the direction of movement.
        Parameters:
        dc - Current draw context.
        symbolPoint - Symbol position in model coordinates.
        heading - Direction of movement, as a bearing clockwise from North.
        length - Length of the indicator line, in pixels.
        frameHeight - Height of the symbol's bounding rectangle, in pixels.
        Returns:
        List of screen points that describe the speed leader line.

      • computeDirectionOfMovement

        protected static Vec4 computeDirectionOfMovement​(DrawContext dc,
                                                 Vec4 symbolPoint,
                                                 Angle heading,
                                                 double length)
        Compute a vector in the direction that a symbol is moving.
        Parameters:
        dc - Current draw context.
        symbolPoint - Symbol position in model coordinates.
        heading - Heading as a bearing clockwise from North.
        length - Length of the leader line, in pixels. The computed vector will have magnitude equal to this distance in pixels multiplied by the size of a pixel (in meters) at the position of the symbol relative to the current view.
        Returns:
        A vector that points in the direction of a symbol's movement.

      • getDefaultGraphicMaterial

        public static Material getDefaultGraphicMaterial​(SymbolCode symbolCode)
        Determines a default color to apply to a symbol. MIL-STD-2525C section 5.5.1.1 (pg. 37) states that obstacles should be displayed in green, friendly entities in black or blue, and hostile entities in red. This method return green for obstacles and neutral entities, black for friendly entities, red for hostile entities, and yellow for unknown and pending entities.
        Parameters:
        symbolCode - Symbol for which to determine color.
        Returns:
        Default material for the specified symbol.

      • isObstacle

        protected static boolean isObstacle​(SymbolCode symbolCode)
        Indicates whether or not a symbol code identifiers an Obstacle. Obstacles defined in the Mobility and Survivability category of MIL-STD-2525C Appendix B.
        Parameters:
        symbolCode - Symbol code to test.
        Returns:
        True if the symbol code represents an obstacle, otherwise false.
