| 摘 要： | 针对CityGML(City Geography Markup Language)城市模型实时可视化问题,提出一种流式读取与数据绑定结合的快速解析办法以及多线程并行处理的数据加载策略,通过将模型数据重新组织成Direct3D网格对象实现了对三维图形的高效渲染。实验部分给出了.Net平台下基于C#与Direct3D的三维可视化结果,证明了方法的有效性。

| Abstract: | To solve the problem of real time visualization of 3D city model based on CityGML,a rapid data parsing strategy which combined the streamed reading and data binding techniques was proposed together with a multi-threaded parallel data loading strategy.Moreover,efficient rendering was achieved through reorganizing the model into Direct3D Mesh.The experimental results implemented by using C# and Direct3D under the.Net platform show the effects of the 3D visualization which verify the effectiveness of the proposed methods. |
