Specifies a direction by means of a vector, where X, Y and Z refer to the global axes and the sign of a component corresponds to the +ve or -ve direction on that global axis.
Note Only the direction of the vector, not its magnitude, will be used by the program. This means, for example, that (0.1,0,0) is equivalent to (1,0,0). If the vector has more than one component, it is not necessary to describe a unit vector, for example (1,1,0) is equivalent to (0.707,0.707,0).
