Embodiment 1
[0036] refer to figure 2 , a multi-level linkage method of virtual forest simulation information based on scene roaming, the method is:
[0037](1) Use the forest growth model to calculate the biomass of each tree, and search the tree visualization model corresponding to the tree biomass from the scene database according to the calculated biomass of each tree, and draw a virtual forest scene on the computer screen; The forest growth model is at least one of fine-grained, medium-grained, and coarse-grained forest growth models, and the tree biomass refers to the total amount of organic matter accumulated by trees in a certain period of time, which can be accumulated per unit time. The average quality is represented, and the tree visualization model can be a three-dimensional tree model, a tree picture or other symbols representing trees;
[0038] (2) Automatically identify simulation events in the process of real-time interactive roaming in the virtual forest simulation scene...
Embodiment 2
[0045] refer to figure 1 , a system for implementing the multi-level linkage method of virtual forest simulation information based on scene roaming as described above, the system is composed of a simulation application layer 1 and a data layer 2. Simulation application layer 1 provides virtual forest simulation process and parameter visualization management and maintenance functions, including simulation parameter module 3, growth simulation module 4, information linkage module 5, roaming event monitoring and management module 6, policy management module 7, growth model Management module 8, scene management module 9, etc.; data layer 2 provides growth model data information in the process of virtual forest simulation, and scene data and linkage strategy information when converting forest scene simulation information with different scene granularity, including scene linkage strategy library 10. Growth model library 11 and scene database 12.
[0046] The growth model management...
