| + | Having experience with first and second generation [[Multiplayer|multiplayer]] projects in [[IRCMFD]] and [[MultiOrb]], the [[CCCP Fleet|CCCP Team]] were looking for multiplayer strategies for their in-development simulator [http://openkosmos.sourceforge.net/ Kosmos]. Two methods were suggested. The first was developed wholly internally by Russell Smith based on plans for [[MultiOrb]] before it was shelved. The second, a 'thin client' system, had no previous developments to build on, so a plugin for Orbiter was made to obtain test results. | ||

The concept of the ''thin client'', however, means Orbiter is only used as the rendering engine and supplier of basic ship-local physics (rotation, thrust, docking etc.). A central physics server determines the dynamics, specifically the orbit, and controls the flow of data to the clients providing a jitter-free inter-user experience at the expense of slight lag when executing translations. | The concept of the ''thin client'', however, means Orbiter is only used as the rendering engine and supplier of basic ship-local physics (rotation, thrust, docking etc.).
