Noob question…can anyone please tell me how to do this without the idle function…

void idle(){
rY += 0.05;
}

how did you do fix it?

void timer(int v) {
  if (animate) {
    rY2 += 0.05;
    if (rY2 > 360.0) {
      rY2 -= 360.0;
    }
    glutPostRedisplay();
  }
  glutTimerFunc(1000/FPS, timer, v);
}

then in your main instead of glutIdleFunction(idle)

just put glutTimerFunc(100, timer, 0);

declare FPS and set as 60 or anything you want…hope it helps
