基于OSG的三维数字地球引擎设计与实现

Design and Realization of 3D Engine for Digital Earth Based on OSG

针对三维数字地球引擎的建设需求,结合场景图形管理技术和软件构件化设计思想,进行了面向实际工程应用的三维数字地球引擎框架结构设计和关键技术及解决途径分析。该引擎将三维地理信息、虚拟现实、粒子效果、立体声效、流媒体视频等进行一体化集成实现,便于适应复杂环境的模拟、分析和监视,应用前景广阔。

To meet requirements of 3D engine for digital earth, this paper designs a 3D engine based on the management of scene graph and software component engineering. This paper introduces the frame structures of the 3D engine for project application and analyzes its key techniques. The engine integrates and realizes 3D geographic infonnations, virtual reality, particle system, stereo audio and streaming media video, convenient to simulation, analysis and monitoring for complex environment, and it has a bright application prospect.
