Glavni problem vezan za pronalaženje geometrijskih preklapanja u Pythonu je taj što biblioteka ne pruža jednostavan način da se identifikuje koji se poligoni preklapaju. Osim toga, biblioteka ne pruža način da se odredi obim preklapanja.

Biblioteke geometrije
Postoji nekoliko Python biblioteka koje se fokusiraju na geometriju. Ove biblioteke se mogu koristiti u različite svrhe, kao što su crtanje oblika, izračunavanje udaljenosti i uglova i još mnogo toga. Neke od najpopularnijih Python biblioteka geometrije uključuju:
PyGDX: Ova biblioteka se koristi za razvoj igara i aplikacija koristeći OpenGL. Uključuje značajke za crtanje oblika, izračunavanje udaljenosti i uglova i još mnogo toga.
NumPy: Ova biblioteka se koristi za matematičke operacije nad nizovima brojeva. Sadrži funkcije za rad sa tačkama, linijama, poligonima i još mnogo toga.
