摘要
介绍用MultiGenGreaterPro建模软件和VegaAPI编程技术开发露天矿生态重建视景仿真系统所采用的几项计算机处理方法和关键技术。针对露天矿生态重建特点 ,采用层次型与面向对象相结合的三维数据结构 ,构造露天矿生态重建视景仿真模型 ;采用LOD技术为露天矿虚拟环境中的地形和建筑物构造多层次、多分辨率的细节模型 ,对三维型地形模型按数据块进行简化 ,以适应不同硬件平台和视觉特性的分辨率需求 ;采用Vega软件实现露天矿三维动态全景图显示与实时驱动的基本方法 ;
It is a new try to develop open-pit mine ecological reconstruction simulation system in which both MultiGen CreterPro modelling software and VegaAPI programming method are used in virtual simulation field.Several computer treatment methods and key techniques which are adopted during development process are introduced in this paper.Open-pit mine ecological reconstruction scenery simlation system is modelled by adopting hierarchical model combined with object-oriented data structure?In order to construct the multilevel and mltiresolution model for the terrain and architecture in the virtual environment,the LOD technique is adopted.Basic methods,using Vega to realise open-pit mine 3D dynamic panoramic displaying and the real-time driving,are especially discussed.Ecological reconstruction planning alternatives can be designed by use of the entity mark technique.
