电网三维模型简化与渲染优化方法研究

摘要

随着三维可视化技术在电网地理信息系统(Geographic Information System, GIS)中的广泛应用，电网三维模型成为除基础地理数据之外电网三维GIS系统承载的又一重要数据。本文设计并实现了针对于电网三维模型简化机制，对各种精细的设备模型，在保持原设备不失真的情况下进行建模的自动裁剪。结合面向对象的模型数据动态调度技术，形成基于批量电网三维模型的渲染引擎，实现电网设备模型的高效渲染。%With the 3D visualization technology is widely used in the power grid GIS,power grid three-dimensional model become another important the basic geographic data used in he power grid 3D GIS. A three-dimensional grid for the model to simplify the mechanism is designed and implemented in this article, that can cut a variety of sophisticated equipment model automatically while maintaining the original equipment without distortion. It implemented equipment model rendering efficiently, and formed power grid rendering engine, combined with object-oriented data model dynamic scheduling techniques.
