3D Game Programming All in One (Course Technology PTR Game Development Series)

Of course, a cool car needs cool wheels. There's not much to them, so I invite you to model your own wheel for use on the car. You, of course, may decide to make a complex model, but there is really no need—a lot can be done with a decent skin. A collision mesh is not needed, but do make sure that the wheel is oriented in the views the same as it would appear if attached to the car. Also ensure that the axle of the wheel and the midline of the tire are aligned with the origin bug.
