If only there was some way we could create some sort of arrangement of 3D models and place a virtual camera within the arrangement. We could introduce some physics simulation and make the position of the virtual camera move and render what it sees to the user.

If such a system were possible, it seems like it would be far better at consistency and realism, since it could be fine tuned and hand crafted to best represent the desired world. It could be used to make interactive experiences, games, perhaps even feature films!

Alas.
