anbei der Quellcode...komme einfach nicht weiter, was so ziemlich demotivierend ist. Die Anzeige der View sind 2 Dreiecke eins schwarz das andere bunt, weiss jemand von euch wo der Fehler liegt? Ach so, bitte keine Tipps zu pygame oder pyglet usw., das Projekt soll rein in Opengl sein. Ich wäre sehr dankbar wenn mir hier jemand weiterhelfen könnte.
