thick_line(x,y,thickness)
This function returns the coordinates that outline the thick line surrounding an input line at a fixed distance. For an intuitive sense, think of tracing a thin, pencil-drawn line with a thick marker.
The input line is defined by ordered x and y coordinates. The output coordinates are all a specified distance from the closest part of the specified input line. The output is formatted to be used with the patch command.
Each vertex is surrounded by a circle (approximated by a many-sided polygon), and the line segments with rectangle. The polygons are joined with polybool('union',...) from the mapping toolbox.
For example:
cla
axis([0,10,0,10])
axis equal
[x,y] = ginput();
plot(x, y, '*-')
[x_out, y_out] = thick_line(x, y, 0.5);
p_obj = patch(x_out, y_out, [0.7, 0.1, 0.1]);
set(p_obj, 'FaceAlpha', 0.5)
