Model Arrow defines an arrow that is dynamically visualized at the defined location (see variables below).

The dialog variables R, r,
r_tail, r_head, diameter,
color and specularCoefficient 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.Arrow arrow(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.
