摘要
针对空间数据可视化问题，简要介绍Direct3D固定图形渲染管线和绘制程序结构，研究和探讨了虚拟三维地形实时构建、渲染、漫游及其实现技术，采用规则格网（Regular square grid，RSG）模型来组织和表达地形数据，同时向场景添加天空和直升机模型，以增强逼真效果，通过构建虚拟相机来控制场景漫游。
The fixed pattern rendering pipeline and drawing program of Direct3D for spatial data visualization are briefly introduced, and real-time construction, rendering, roaming and implementation of virtual 3D terrain are studied and discussed. Regular square grid model is employed to organize and render the terrain data, and the models of dome sky and helicopter are added to virtual scene to enhance reality effect. Finally, a virtual camera is designed and used to control virtual scene roaming.
