[Qt5, OpenGL] Texturowanie sześcianu - problem! » 2017-04-21 10:31:48 Zabrałem się za pisanie bardzo prostego programu, którego zadaniem jest oteksturowanie sześcianu. Program ładnie wyświetla bryłę sześcianu ale niestety bez tekstur. Czy ktoś bardziej obeznany z OpenGl mógłby rzucić okiem na kod tego programu i powiedzieć co źlę zrobiłem i jak to naprawić? Przypuszczam że głównym podejrzanym będzie funkcja wczytująca teksturę ale nie wiem tego na pewno… #-------------------------------------------------
