DoubleArrow

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

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Model DoubleArrow defines a double arrow that is dynamically visualized at the defined location (see variables below).

model Visualizers.Advanced.DoubleArrow

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.DoubleArrow doubleArrow(diameter = sin(time));

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, 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 (will be replaced by a color editor).

Inputs (7)

R	Default Value: Frames.nullRotation() Type: Orientation Description: Orientation object to rotate the world frame into the arrow frame
r	Default Value: {0, 0, 0} Type: Position[3] (m) Description: Position vector from origin of world frame to origin of arrow frame, resolved in world frame
r_tail	Default Value: {0, 0, 0} Type: Position[3] (m) Description: Position vector from origin of arrow frame to double arrow tail, resolved in arrow frame
r_head	Default Value: {0, 0, 0} Type: Position[3] (m) Description: Position vector from double arrow tail to the head of the double arrow, resolved in arrow frame
