public class PnCellOperator

extends PjProject

implements java.lang.Runnable

Implements a cellular automata on the triangles of an element set.

Version:

27.06.00, 2.10 revised (ur) Marked cells output by ElementTag added. 02.05.00, 2.00 revised (kp) Class derived from PjProject in order to reuse interface methods.
02.05.00, 1.20 revised (kp) Removed the static getDialog() method which implicitly constructed a PnCellOperator.
02.04.00, 1.10 revised (kp) PdColor replaced with Color.
18.09.99, 1.01 revised (kp) Added two additional method to fulfill PvPickListenerIf.
02.08.99, 1.00 created (ur)
