The wander effect keep a point over a sphere in front of the object of radios wander_radios and with distance wander_distance this point is stored in the local space of the object because an update in the position of the object should not affect the coordinates of this point. The wander function in each update insert a noise in this point and to generate the effect of wander it calls the function seek that receives a point in global space and apply a force in the object in that direction. Therefore is needed to convert the wander point from local space to global space.
