摘要
本文论述了二维GIS的三维可视化技术的实现方案,重点阐述了其中涉及的关键技术模块,如地形、纹理、模型、相机等。旨在提出一种轻量化的简洁高效的实现方案,并在数据接口和渲染效率优化方面也作了相关论述。实验项目证明本文提出的技术方法是可行的,并可用于工程实践。
This paper discusses an efficient way to visualize 2D-GIS in 3D space,especially describing several key modules involved,including terrain,texture,3D-model and camera motion.We mainly propose a light but available solution to realize 2D-GIS in a 3D environment with 3D-models.Additionally,the optimizing for rendering efficiency and the interface with standard model format are concerned as well.These techniques and methods have been proved to be workable and practicable.
