Optimization method of virtual sand table background server based on unity 3D

In recent years, the digital sand table has gradually replaced the entity sand table and become a new way of 3D scene sand table display. Unity3d platform has the characteristics of accurate data expression, strong expressiveness and interactivity. Therefore, the optimization method of virtual sand table back-end server based on unity3d is optimized. In this paper, a regional digital sand table is designed and implemented, and the key technologies are analyzed and studied. A set of technical schemes of using unity3d platform to build digital sand table is summarized and verified. The experimental results show that, the optimization method of virtual sand table background server based on unity3d has high practicability and fully meets the research requirements.
