This information is part of the Modelica Standard Library maintained by the Modelica Association.
With model Lines a set of dynamic lines is defined
that are located relatively to frame_a. Every line
is represented by a cylinder. This allows, e.g., to define simple shaped
3-dimensional characters. Note, if the lines are fixed relatively to frame_a,
it is more convenient to use model Visualizers.Internal.FixedLines.
An example for dynamic lines is shown in the following figure:
The two letters "x" and "y" are constructed with 4 lines
by providing the following data for input variable lines
lines = {[0, 0; 1, 1],[0, 1; 1, 0],[1.5, -0.5; 2.5, 1],[1.5, 1; 2, 0.25]}
Via vectors n_x and n_y a two-dimensional coordinate system is defined. The points defined with variable lines are with respect to this coordinate system. For example "[0, 0; 1, 1]" defines a line that starts at {0,0} and ends at {1,1}. The and color of all line cylinders are identical and are defined by parameters.
