Makeshift visualizers for display of three-dimensional fonts using cylinders
This package contains components to construct 3-dim. fonts with "cylinder" elements for the animation window. This is a makeshift as long as the support of 3-dim. fonts is not specified in the Modelica language. The components are used to construct the "x", "y", "z" labels of coordinates systems in the animation.

Modelica.Mechanics.MultiBody.Visualizers.Internal.FixedLinesVisualizing a set of lines as cylinders (e.g., used to display characters)
With model FixedLines a set of lines is defined
that are located relatively to frame_a. Every line
is represented by a cylinder. This allows to define simple shaped
3-dimensional characters. An example is shown in the
following figure:
The two letters "x" and "y" are constructed with 4 lines
by providing the following data for parameter lines
lines = {[0, 0; 1, 1],[0, 1; 1, 0],[1.5, -0.5; 2.5, 1],[1.5, 1; 2, 0.25]}
Via parameter vectors n_x and n_y a two-dimensional coordinate system is defined. The points defined with parameter 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 diameter and color of all line cylinders are identical.

Modelica.Mechanics.MultiBody.Visualizers.Internal.LinesVisualizing a set of lines as cylinders with variable size, e.g., used to display characters (no Frame connector)
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.
