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.
