Problem mit for bzw. foreach -Schleife bei Knotenpunkte (nodes)
Dies ist der bisherige Quelltext für jenes (stark erweiterte) Trapez:
Bisher klappt es ganz gut, nur wie man die letzten inneren Schnittpunkte in einer Schleife reinpackt, um diese ellenlange Schreiberei sich zu ersparen, will noch nicht so recht funktionieren. Mein Versuch steht vor Beginn der Liste in Kommentaren gesetzt.

Problem mit for bzw. foreach -Schleife bei Knotenpunkte (nodes)
Dies ist der bisherige Quelltext für jenes (stark erweiterte) Trapez:
Bisher klappt es ganz gut, nur wie man die letzten inneren Schnittpunkte in einer Schleife reinpackt, um diese ellenlange Schreiberei sich zu sparen, will noch nicht so recht funktionierten. Mein Versuch steht vor Beginn der Liste in Kommentaren gesetzt.
