System and method to synchronously display 3D object information on plural screens of plural computers

A 3D synchronous display method with plural computers and plural screens, wherein the plural computers are connected over a network and provided with display screens comprising a main window and sub-windows, and the method comprises:

• maintaining an operation information table on each of the computers connected over the network in response to an initiation message from a joining computer connected over the network, wherein the initiation message comprises 3D object information and display angle-of-view information;
• the operation information table comprises an IP address of each of the computers in the network and its operation status information;
• and the operation status information comprises peer status information, master status information or slave status information;
• loading respectively on the computers in the network a 3D object in response to the initiation message, and drawing by each of the computers in its main window the 3D object according to a corresponding display angle-of-view information and also generating a sub-window in which the 3D object with a different angle-of-view of other computers in the network than a current computer is drawn;
• receiving a 3D object trigger instruction submitted from a user to any of the computers in the network;
• if the operation status information of the computer receiving the instruction is peer status information, changing the peer status information to master status information, and submitting a control privilege request message to other computers recorded in the operation information stable;
• receiving by the other computer the control privilege request message, and changing its operation status information to slave status information;
• receiving a 3D object operation instruction submitted from the user to the computer with master status information, and updating the drawings of the 3D object respectively in the main window and the sub-window of the current computer in response to the instruction;
• and
• generating from the drawing update operation and sending a corresponding operation request to a corresponding computer with slave status information, and updating by the computer with slave status information the drawings of the 3D object respectively in its corresponding main window and sub-window in response to the operation request.
