All animated algorithms have been implemented in the course of bachelor projects under the supervision of Oswin Aichholzer. They are intended to support the algorithm courses given at Graz University of Technology. Disclaimer: The algorithms have been carefully implemented, but there is no guarantee that they are correct in all details. So always use them with a healthy portion of critical curiosity. If you encounter any unexpected behavior please consult the course material (slides and videos). If you cannot resolve the problem, then please contact your TAs or lecturers.
