A 3D-vector containing double values. Vector3D is used for anything requiring a three dimensional vector with optional accuracy, e.g. an acceleration-vector. According to the ENU (East-North-Up) System, a value is positive in right, up, front direction and negative in left, down, rear direction. When representing rotations then the value represents the rotation along the named axis in angular speed with the rotation in mathematical positive direction facing the positive end of the axis is represented by a positive value. From the vehicles reference point, increasing any dimension of a rotation vector results in “yaw to the right” (heading), “roll to the left” (cross-slope) and “pitching to the front” (slope). A longitudinal value always refers to the rear-front-axis in longitudinal direction, a transversal value refers to the left-right axis and a vertical value refers to the down-up axis.
