摘要
在对移动三维GIS技术分析的基础上,选取OSG渲染引擎作为真三维开发平台。重点对实景三维数据、osg模型组织方式、海量数据显示等关键技术进行深入研究,确定了基于Android平台加载海量真三维数据的可行性。最后,将osg三维引擎成功移植到Android端,完成了真三维场景的加载与显示。实验结果表明,海量真三维数据在Android平台上运行流畅、图形质量高、响应速度快,扩展了实景三维数据的应用范围。
Based on the analysis of mobile 3D GIS technology,we choose OSG rendering engine as the true 3D development platform.Focus on the real three-dimensional data,OSG model organization,mass data display and other key technologies in-depth study to determine the feasibility of loading huge amounts of true three-dimensional data based on the Android platform.Finally,the OSG three-dimensional engine is successfully ported to the Android side,completed the true three-dimensional scene loading and display.The experimental results show that the massive real 3D data runs smoothly on the Android platform with high graphics quality and fast response,which expands the application range of real 3D data.
