У меня проблема с созданием анимации вращающихся кубиков в JAVA в OpenGL. Куб виден, окрашен и вращается, но мне также нужно с каждой стороны разную текстуру. На данный момент я не вижу текстуры там, но когда я использую println, кажется, что все текстуры были инициированы и буферизованы.JAVA OpenGL 3D Cube несколько текстур

Было бы лучше опубликовать sscce: http://sscce.org Скорее позвоните GLU.createGLU (GL), чтобы правый подкласс GLU использовался, даже если вы используете другой профиль с другой реализацией GL, это более надежное будущее , – gouessej
