摘要：

This paper explores how the reconstruction of special history scenario will be applied in online education. After investigating various virtual reality techniques including design of virtual educational system, reconstruction of virtual scene, management of scene, AI, lightweighting for 3D model and light shadow rendering, we build an online education platform for touring a web3D virtual battlefield scenario called Huangyangjie in China. We firstly present the solution and scheme for rebuilding the web 3D battlefield Scenario using lightweight 3D models. Secondly, we present voxel of interesting (VOI) scene management strategy based terrain-voxel-model uniform structure. Finally, we optimize A* algorithm in AI management process and present Parallel-Split Variance Shadow Mapping (PSVSM) algorithm based on sparse voxelization in real-time Web-based rendering.
