248 Chapter 11 The Rigid-Body Physics Engine
The aerodynamic tensor isn ’t sufficient for games that intend to simulate flight or
sailing accurately. We’d need to do a lot more work for that. But as they stand they are
perfectly sufficient for games that are not intended to be realistic.
The situations I chose for this chapter were selected carefully , however, not to
embarrass the physics engine. As it stands, our engine is less capable than the mass

collisions back in. Unfortunately, w ith rotations in place this becomes a significantly
more complex process than we saw in Chapter 7. It is worth taking the time to get it
right. In that spirit, before we consider the physics of ...
