Représentation des triangulations

Représenter des triangulations et interagir avec elles

Représentez des données de triangulation 2D ou 3D sous forme d’objet triangulation et utilisez des fonctions d’objet pour calculer des quantités géométriques. Vous pouvez visualiser la triangulation et utiliser des fichiers STL pour lire et écrire des données de triangulation.
