If your object is at coordinates a, b, c, and you wish to face towards d,
e, f in the global coordinate system, then call
glLoadIdentity();
gluLookAt(a, b, c, d, e, f, 0, 1, 0);
The last three parameters define the vector that will be pointing up
(towards the top of your screen) when the resulting image is drawn.
