大规模城市场景数据在Unity 3D中加载及渲染技术的应用

Application of Loading and Rendering Technology of Large Scale City Scene Data in Unity 3D

随着电力三维应用功能的不断深化,大规模场景数据的动态加载成为电力三维应用中需要解决的问题。主要讨论了大规模城市场景数据在三维场景中的加载及渲染技术,根据城市建筑数据的特点,主要研究两部分内容:城市建筑数据的处理;海量城市模型渲染技术的实现。该系统构建了基于Unity 3D的三维渲染引擎,实现了大规模城市场景的高效渲染模块的开发。该系统作为电力三维系统的一部分,能够实现变电站、架空线、地下电缆等周边城市建筑模型的快速生成及高效展示,有助于深化其在架空线路、电缆通道等业务的应用。

With the deepening of power 3D application function,dynamic loading of large-scale scene data had become a problem that needed to be solved in power 3D application.This paper mainly discussed the loading and rendering technology of large-scale urban scene data in 3D scene.According to the characteristics of urban building data,the study focused on two aspects:the processing of urban building data;the rendering technology realization of massive city model.The system builded a 3D rendering engine based on Unity 3D and realized the development of efficient rendering module for large-scale urban scenes.As a part of the three-dimensional power system,the system could realize the rapid generation and efficient display of the surrounding urban building models such as substations,overhead lines and underground cables,and contribute to the deepening of business applications such as overhead lines and cable channels.
