Nope. A point is a 0-dimensional entity, because you cannot move along it. A line is a 1-dimensional entity, because you can move along it with one degree of freedom. A surface (i.e. a closed polygon) is a 2-dimensional entity, because you can move inside along it with two degrees of freedom. Now, in a 2-dimensional realm (i.e. a plane), you can have 0-, 1-, and 2-dimensional things. Specified with 2-dimensional coordinates. -- ---------------------------------- Iván Sánchez Ortega <[EMAIL PROTECTED]> No hacer nada es el camino para no ser nadie
