This article will explain in detail how to realize the split-screen system technology in the secondary development of TE. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

In the development of three-dimensional system, the system is required to display on multiple screens, the content on each screen is different, and the linkage between screens is needed, or in a large screen system, the whole screen needs to be displayed by several computers, and the content also needs to interact with each other, which requires the use of split-screen technology in the development process.

Of course, the technology is universal, not necessarily to do te three-dimensional system, other systems will also have this kind of demand.

The same system, in the development, can also be divided into several subsystems, so that a large system can be divided into several processes, which can make full use of computer resources.

Similarly, the system running on a large screen needs to be controlled by a mobile phone or pad, which also involves split-screen operation.

According to the above application scenario, let's talk about how to implement it technically, according to the mode of CS.

1. Different process programs of the same computer: in the operating system of windows, the communication between processes can be developed by calling windows's api through C #, which can be searched on the Internet and propagated through the process name or form name in windows.

2. Programs of different computers: it is necessary to ensure that the networks of these computers are interconnected, or they can only be solved from the hardware level of the computer. Communication can be carried out through the UDP, TCP or http protocols of the Internet, and the application programs in the computer can cooperate with each other when the operation of these protocols is realized. The same computer mentioned above can also be solved in this way. Is that the network addresses are all the same.

3. Mobile collaboration: the development of UDP, TCP or http protocols is also supported in the system development of mobile phone or pad.

4. Use message queuing: "the full name of MQ is Message Queue, and message queuing (MQ) is a method of application-to-application communication. Applications communicate by reading and writing messages in and out of the queue (for the application's data) without the need for dedicated connections to link them." This is a professional way with high efficiency, such as rabbitmq, Kafka, etc. The message queuing server is built in the network, and the programs in the computer deliver messages according to api.

The same computer program uses different processes to calculate the position of other programs in real time during the movement of the window to ensure that the window looks consistent.

Map location synchronization, through the transfer of coordinates, location positioning, can also achieve a consistent effect.

The api call in the program uses asynchronous execution mode as far as possible to prevent the program from appearing false death. It can simply store the transmitted information and prevent loss.

Messages can be organized into xml or json format, and now the parsing class library of this kind of information is very convenient, and generally speaking, the amount of data in json is smaller than that in xml.
