modelArrow

Visualizing an arrow with variable size; all data have to be set as modifiers (see info layer)

Information

Note: This element is intended to be used in CoordinateSystem only! To visualize an arrow in your model, the best solution is usually to use the visualizer Advanced.Arrow. The only difference between this two visualizers is that the current one does not utilizes outer planarWorld, whereas the other does.

Model Arrow defines an 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.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.

Components

Type	Name	Default	Description
MB.Frames.Orientation	R	MB.Frames.nullRotation()	Orientation object to rotate the planarWorld frame into the arrow frame
SI.Position[3]	r	{0, 0, 0}	Position vector from origin of planarWorld frame to origin of arrow frame, resolved in planarWorld frame
SI.Position[3]	r_tail	{0, 0, 0}	Position vector from origin of arrow frame to arrow tail, resolved in arrow frame
SI.Position[3]	r_head	{0, 0, 0}	Position vector from arrow tail to the head of the arrow, resolved in arrow frame
SI.Diameter	diameter	1/40	Diameter of arrow line
SI.Diameter	headDiameter	diameter*PlanarMechanics.Types.Defaults.ArrowHeadWidthFraction	Diameter of arrow head
SI.Length	headLength	diameter*PlanarMechanics.Types.Defaults.ArrowHeadLengthFraction	Length of arrow head
MB.Types.Color	color	PlanarMechanics.Types.Defaults.ArrowColor	Color of arrow
MB.Types.SpecularCoefficient	specularCoefficient	0.7	Material property describing the reflecting of ambient light (= 0 means, that light is completely absorbed)
