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.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 diameter and color of all line cylinders are identical and are defined by parameters.
