Abstract:

Combining CAVE2 immersive virtual simulation hardware with forest management requirements,a forest virtual simulation system based on CAVE2 was designed and realized,which provided a virtual simulation platform for forest management.The performance and characteristics of CAVE2 hardware system were analyzed,and the overall structure of the developed system was presented.The functions and realization flows of four system modules that were tree morphology and structure,forest landscape,forest growth and forest management simulation,were designed separately.The software system was developed by using the Unity three-dimensional development engine.Taking a sample plot of Chinese fir plantation as the experimental object,system application was carried out.The results showed that this method effectively realized the integration of CAVE2 virtual reality hardware system and Unity visual simulation software system,and could carry out the visual simulation of interactive forest management and growth prediction in immersive three-dimensional virtual simulation environment.This virtual simulation system with immersion and interaction can provide a new scientific research and application platform for forest management,and can be used to guide forest management practices.

Key words: CAVE2, unity3D, virtual simulation system, forest, design and realization
