org.graphstream.ui.geom.Point3
3D point. A Point3 is a 3D location in an affine space described by three values along the X, the Y and the Z axis. Note the difference with Vector3 wich is defined as an array and ensures that the three coordinates X, Y and Z are consecutive in memory. Here there are three separate attributes. Further, a point has no vector arithmetic bound to it (to points cannot be added, this would have no mathematical meaning). @author Antoine Dutot @since 19990829 @version 0.1
