The assignment involves basic 2D computer graphics used in combination with fundamental algorithmic elements to create a simple drawing application. Students are first asked to create a data structure and appropriate functions replicating the operations of a Turtle graphics system and then to use this turtle for drawing either fractals or spirolateral curves.10.2312/eged.2018100539-42
