При умножении матриц в общем случае A x B != B x A.
Попробуй model_matrix * view_matrix.
Без VIEW_MATRIX будет все ок, но камеру нельзя будет перемещать в пространстве. |
да знаю я это пробывал поразному...
Запилил почти нормально, но вот смущает следующее:
низ какой то странный, а бока вроде бы нормальные
