摘　　要：为了实现牙颌模型的三维数据可视化,通过计算机逼真的显示牙列形态,并进行交互测量及变形等操作。在口腔修复体计算机辅助设计中,以OpenGL为渲染工具,结合自主设计的牙颌模型三维激光扫描仪获取的点云数据,采用基于B样条曲面的三维重建技术,以Visual C++为开发工具实现数字化牙颌模型的三维可视化。以Visual C++和OpenGL为工具,减少了程序设计难度,提高了执行效率,图形显示更加逼真流畅。本系统的设计满足了口腔医生的需求,给患者带来了便利,并促进了口腔修复体的开发制作。To achieve the three- dimensional data visualization of dental models, use computer- simulated display of dentition, and realize interactive measurement and deformation operation, and so on. In computer aided design of dental prosthesis, takes OpenGL as an exaggerating tool, combining the acquired point cloud data from the dental 3D laser scanner which was independent designed, which adopts the 3D reconstruction technique based on B - spline, and realizes the 3D dental visualization with Visual C ＋ ＋ as the developing tool. Take Visual C ＋ ＋ and OpenGL as a tool , reduced the difficulty of the design process, improved the efficiency, smoother graphics more realistic. The design of the system meet the needs of the oral doctors, brought the convenience to the patient and promote the development of prosthodontics production.
