I am trying to rotate a 3D model in both forward (counter-clockwise) and reverse

  • 0

I am trying to rotate a 3D model in both forward (counter-clockwise) and reverse (clockwise) rotation directions in orthographic mode. glRotatef() automatically executes a forward rotation but I cannot get a reverse rotation. I have tried the following methods and none of them give me results:

   //(Provide a negative rotation angle of -1 degree)
    glrotatef(-1.0, 0.0, 1.0, 0.0);

    //(Set a negative axis)
    glrotatef(1.0, 0.0, -1.0, 0.0);

Is this a limitation in OpenGL ES 1.1? How can I get REVERSE (clockwise) rotation in OpenGL ES?
