Do you mean that in your scene the objects appear to be bent outward? In
that case, it is because the camera is pointing slightly upwards and you
have a case of parallax view (like in a real world camera, by the way).
In your case, where z seems to be up, you can rapidly solve this by using
the same z-value for location and look_at. The drawback is that your horizon
is then in the exact middle of the image, but for a start that will do.
There is a little utility somewhere in one of the newsgroups that will
straighten vertical objects in such cases. I shall have a look...
