FixedLines
Visualizing a set of lines as cylinders (e.g., used to display characters)
Library
Modelica/Mechanics/MultiBody/Visualizers/Internal
Description
With model FixedLines a set of lines is definedthat are located relatively to frame_a. Every lineis represented by a cylinder. This allows to define simple shaped3-dimensional characters. An example is shown in thefollowing figure:
The two letters "x" and "y" are constructed with 4 linesby 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-dimensionalcoordinate system is defined. The points defined with parameterlines 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.
