1258 // From http://wiki.secondlife.com/wiki/Linden_Vehicle_Tutorial:
1259 // The vertical attractor feature must be enabled in order for the banking behavior to
1260 // function. The way banking works is this: a rotation around the vehicle's roll-axis will
1261 // produce a angular velocity around the yaw-axis, causing the vehicle to turn. The magnitude
1262 // of the yaw effect will be proportional to the
1263 // VEHICLE_BANKING_EFFICIENCY, the angle of the roll rotation, and sometimes the vehicle's
1264 // velocity along its preferred axis of motion.
1265 // The VEHICLE_BANKING_EFFICIENCY can vary between -1 and +1. When it is positive then any
1266 // positive rotation (by the right-hand rule) about the roll-axis will effect a
1267 // (negative) torque around the yaw-axis, making it turn to the right--that is the
1268 // vehicle will lean into the turn, which is how real airplanes and motorcycle's work.
1269 // Negating the banking coefficient will make it so that the vehicle leans to the
1270 // outside of the turn (not very "physical" but might allow interesting vehicles so why not?).
1271 // The VEHICLE_BANKING_MIX is a fake (i.e. non-physical) parameter that is useful for making
1272 // banking vehicles do what you want rather than what the laws of physics allow.
1273 // For example, consider a real motorcycle...it must be moving forward in order for
1274 // it to turn while banking, however video-game motorcycles are often configured
1275 // to turn in place when at a dead stop--because they are often easier to control
1276 // that way using the limited interface of the keyboard or game controller. The
1277 // VEHICLE_BANKING_MIX enables combinations of both realistic and non-realistic
1278 // banking by functioning as a slider between a banking that is correspondingly
1279 // totally static (0.0) and totally dynamic (1.0). By "static" we mean that the
1280 // banking effect depends only on the vehicle's rotation about its roll-axis compared
1281 // to "dynamic" where the banking is also proportional to its velocity along its
1282 // roll-axis. Finding the best value of the "mixture" will probably require trial and error.
1283 // The time it takes for the banking behavior to defeat a preexisting angular velocity about the
1284 // world z-axis is determined by the VEHICLE_BANKING_TIMESCALE. So if you want the vehicle to
1285 // bank quickly then give it a banking timescale of about a second or less, otherwise you can
