hmm, I'm not sure that I can explain you in english what is a dimension ...
it is the minimal number of vectors needed to give the coordinates of a point
if you need only one vector, then there is one dimension (x)
if you need two vectors, then there are two dimensions (x,y)
if you need three vectors, then there are three dimensions (x,y,z)
some people say that the fourth dimension is the time, but is the time a vector ? maybe .. maybe not .. who knows ? I think that our mind can understand only three dimensions, if there is another one, how could we know ?
oh, I forgot to tell you : it is a very good code
