Arrow
Visualizing an arrow with variable size; all data have to be set as modifiers (see info layer)
Library
PlanarMechanics/Visualizers/Advanced
Description
Model Arrow defines an arrow that is dynamicallyvisualized at the defined location (see variables below).
The dialog variables R, r, r_tail,r_head, diameter, colorand specularCoefficientare declared as (time varying) input variables.If the default equation is not appropriate, a correspondingmodifier equation has to be provided in themodel 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 range0 .. 255.Predefined colors fromTypes.Defaultsare used throughout the library to get a coherent visualization.
