ArrowVisualizing an arrow with variable size |

Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Model Arrow defines an arrow that is dynamically visualized at the defined location (see variables below). If you want an arrow representing something that is not a relative position, use Vector instead.
The dialog variables R, r, r_tail, r_head, color,
specularCoefficient, and headAtOrigin
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(r_head = {sin(time),cos(time},0});
Variable color is an Integer vector with 3 elements,
{r, g, b}, and specifies the color of the shape.
{r, g, b} are the "red", "green" and "blue" color parts.
Note, r, g and b are given in the range 0 … 255.
The predefined type
MultiBody.Types.Color
contains a menu definition of the colors used in the MultiBody
library together with a color editor.
