Bonjour à tous,
Je viens de créer une début de jeu en réalité augmentée, avec la SFML et OpenCV.
L'ensemble tourne bien, mais j'aimerai savoir comment je peux améliorer mon code (Template, Fonctions, Classes), pour aller plus vite et ne pas utiliser inutilement de la mémoire.
Je vous joins le code:

Qu'en pensez-vous ?
Peut-on l'améliorer ?
Merci pour votre aide.
