The diagram above depicts a wheel centered at "C" that has hit an inclined plane at point "X". The inclined plane has unit normal "N", while the suspension direction has unit vector "S". The unit vector from the wheel center to the hit point is "D". Hit points are analyzed by comparing the unit vectors D and N with the suspension direction S. This analysis is performed in the contact modification callback PxVehicleModifyWheelContacts (when enabled) and in PxVehicleUpdates (when non-blocking sweeps are enabled). If the angle between D and S is less than pointRejectAngle the hit is accepted by the suspension in PxVehicleUpdates and rejected by the contact modification callback PxVehicleModifyWheelContacts. If the angle between -N and S is less than normalRejectAngle the hit is accepted by the suspension in PxVehicleUpdates and rejected by the contact modification callback PxVehicleModifyWheelContacts.
pointRejectAngle | is the threshold angle used when comparing the angle between D and S. |
normalRejectAngle | is the threshold angle used when comparing the angle between -N and S. |

Reconfigure the vehicle to reflect a new center of mass local pose that has been applied to the actor. The function requires (i) the center of mass local pose that was last used to configure the vehicle and the vehicle's actor, (ii) the new center of mass local pose that has been applied to the vehicle's actor and will now be applied to the vehicle, and (iii) the direction of gravity (0 for x-axis, 1 for y-axis, 2 for z-axis)
