Model DoubleArrow defines a double arrow that is dynamically visualized at the defined location (see variables below).
The variables under heading Parameters below are declared as (time varying) input variables. If the default equation is not appropriate, a corresponding modifier equation has to be provided in the model where an Arrow instance is used, e.g., in the form
Visualizers.Advanced.DoubleArrow doubleArrow(diameter = sin(time));
Variable color is a RGB color space given in the range 0 .. 255. Predefined colors from Types.Defaults are used throughout the library to get a coherent visualization.
