Вращающийся вокруг мира 0,0,0 вместо центра объекта

Мой объект вращается вокруг 0,0,0, но я хочу, чтобы он вращался вокруг оси Y.
Я знаю, что есть и другие случаи

Вращение объекта вокруг себя в OpenGL

glRotatef не вращается, как ожидалось

но у меня нет никаких переводов до вращения, но он не работает.

мой РЕДАКТИРОВАНИЕ Код:

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

glRotatef(_angle,0.0f,1.0f,0.0f);
glPushMatrix();

glTranslatef(0.0f,0.0f,-6.0f);
glBegin(GL_TRIANGLES);
//Front
glVertex3f(-1.0f, -1.0f, 1.0f);
glVertex3f(-1.0f, 1.0f, 1.0f);
glVertex3f(1.0f, 1.0f, 1.0f);

glVertex3f(-1.0f, -1.0f, 1.0f);
glVertex3f(1.0f, -1.0f, 1.0f);

glVertex3f(-1.0f, -1.0f, -1.0f);

glLoadIdentity();

/* This is a Cube */
