Put briefly, a servo is a little motor. With the help of RealFlow's MultiServos you can now accelerate and move objects in a physically correct manner. A car is a good example, because everybody is familiar with its driving behaviour and has a basic idea of the concepts behind the technology. In a car, a motor is (normally) powered by fuel. The burning of the fuel creates energy that can be transferred to a drive system. This system will finally accelerate the car and set the vehicle in motion. The reason why the car can actually move is friction. On an even and polished surface, the car's wheels would simply slip. You have certainly already seen this on icy or wet streets. RealFlow'sMultiServos can mimic this behaviour and set any object in motion with physically correct acceleration and even braking forces. MultiServos can also react to changes of direction and interact with the ground texture. e.g. a stony, uneven ground. If you set “Friction” values of both the car wheels and the ground to 0.0 you can also observe that the wheels slip.
