The invention provides a multi-channel synchronous simulation method for a CAVE system based on Unity 3D. The method comprises the steps of designing a CAVE immersive system network topology scheme; creating a large-scale three-dimensional virtual simulation scene by Unity 3D; establishing a camera parameter calculation model by specification and layout of the CAVE immersive system; according to the calculation model, obtaining an initial view field angle, a cutting plane, a conversion matrix and a view cone parameter of a camera corresponding to each screen, and independently configuring when the Unity 3D application program is developed and operated; dynamically updating the viewpoint, the viewing direction and the position of the camera in a frame synchronization mode; and achieving real-time synchronization of game object states in a scene in an event synchronization mode, and CAVE system multi-channel synchronous simulation based on Unity3D; according to the CAVE immersive experience scene based on the transportation, building, manufacturing, game and movie industries developed by Unity 3D, the multi-channel synchronous simulation efficiency is high, the immersion of the experience scene is high, and the method is suitable for the field of product demonstration verification and propaganda and popularization and has great practical value.
Description
technical field [0001] The invention relates to the field of CAVE immersive system simulation, in particular to a multi-channel synchronous simulation method of a CAVE system based on Unity3D. Background technique [0002] The CAVE immersive system includes two system architectures: single-host multi-screen and multi-host multi-screen architecture. For the multi-host multi-screen architecture, it is required to start the simulation software on each host. When the central control system performs scene interaction operations, it needs to synchronize the cameras in real time. Parameters and game object state, enabling multi-pass simultaneous simulation. However, even the common Unity3D real-time interactive content creation and operation platform has not yet provided a practical solution. [0003] With the widespread application of CAVE immersive systems, the requirements for immersive experience of simulation software are gradually increasing. There is an urgent need to carr...
