浅析海量三维模型展示的优化方法
|
摘要
随着近年来数字城市与智慧城市建设的蓬勃发展,作为重要组成部分之一的三维模型建设,用户从质量和数量上都对其提出了更高的要求。在此情况下,海量复杂三维模型的显示及优化成为一个迫切需要解决的瓶颈问题。本文提出了一种基于Skyline的Terra Explorer Pro的海量模型三维场景展示的优化方法,通过二次开发对海量复杂三维模型进行动态优化,得到了较好的展示效果。
In recent years,by the digital city and smart city building rapidly,3D models building is the main part of them,users put forward more requirement about it on quality and quantity. In the instance,how to show and optimize mass and complex 3D models,it is an urgent and key question that need to settle. In this paper,the author puts forward a better method for mass models to show in 3D scene basing on Terra Explore Pro of Skyline,and then,the author optimizes mass and complex models dynamically by secondary development and gets excellent display results.
