|
摘要
为了获取生动、可视化的景观规划方案,设计基于三维虚拟VR技术的景观规划系统。主要从三维景观建模与虚拟VR技术两方面展开虚拟景观规划,构建景观三维模型时,利用点云数据在3ds MAX中构建三维建筑、道路模型,通过缩放、修改模型方式优化虚拟景观场景;设计VR虚拟景观仿真支撑平台时,在VR场景编辑模块中编辑景观虚拟场景,仿真核心工作模块负责地形、流体、阳光雨雪模拟特效,最后采用建模及输出模块输出虚拟景观规划结果。由仿真实验结果得出,该系统可根据地形坡度规划合理的景观数量,处理三维点云数据准确率高达99%,是一种满意度较高的景观规划系统。
A landscape planning system based on the 3D VR technology is designed to obtain a vivid and visualized landscape planning scheme. The virtual landscape planning is carried out mainly from two aspects of 3D landscape modeling and VR technology. The point cloud data is used to build the 3D architecture and road model in the 3 ds MAX during the construction of the 3D landscape model. The virtual landscape scene is optimized by scaling and modifying the model. The VR scene editing module is used to edit the virtual scene of the landscape,the simulation core work module is responsible for the special effect simulation of terrain,fluid,sunlight,rain and snow,and the modeling and output module is used to output the planning result of the virtual landscape during the design of the VR virtual landscape simulation support platform. The results of the simulation experiment show that the system designed in this paper can plan a reasonable number of landscapes according to the terrain slope,and has a 3D point cloud data processing accuracy of 99%,which is a highly-satisfied landscape planning system.
