Code:

---

function update_views()
{
	dist_planar = cos (-camera.tilt) * dist_total;
	camera.pan = player.pan;
	camera.tilt = -70; //play with this value
	camera.x = player.x - cos(player.pan)*cos(-player.tilt)*zoom;
	camera.y = player.y - sin(player.pan)*cos(-player.tilt)*zoom;
	camera.z = player.z + sin(-camera.tilt)*zoom;
	camera.pan = cam_angle;
	camera.roll = 0;
	validate_view();
}

This _should_ work but I've not tested it

EDIT:
which tutorial did you follow?
could you please post a link and I'll might take a look at it to see what the author did intend to do, and how I can help you out.
