WebIt is not a direction (and if it were, it'd be the wrong direction). It doesn't matter where the camera is moved to, it will always look towards that point. The problem here is that you don't want to look at a particular point all the time, you want to look in a particular direction, so you should be using glRotate . WebAlso note that in OpenGL (by default, unless you manually build your own projection matrices to do things differently), the camera looks along the negative z axis. If you move the an object forward by the camera's z axis each frame, you'll actually be moving the ball further and further behind the camera, rather than in front of it.
