【摘要】 本文建立了人眼晶状体的参数化三维几何模型,开发了基于VC++和OpenGL的三维显示系统。首先,根据临床数据构造了一个标准的晶状体模型,然后,通过输入临床获取的特征参数如晶状体直径、厚度、核直径、核偏移等,生成满足特定约束条件和几何拓扑的晶状体模型,从而代表了不同人群的晶状体特征。利用OpenGL图形库实现了晶状体的立体感、透明性和旋转缩放等。本文提出的人眼晶状体参数化建模方法实现了国人虚拟眼晶状体的三维可视化,并为晶状体调节功能研究和手术仿真研究奠定了基础。更多还原

【Abstract】 An interactive and realistic three dimension lens display system based on VC++ and OpenGL which is popular graphical interfaces was developed. Firstly, a standard lens model was constructed based on the published experimental data, moreover, by inputting clinical characteristic parameters, such as lens diameter- lens thickness, nucleus diameter, nucleus thickness, nucleus excursion, a new lens which satisfied certain restricting conditions and geometry topology relation was generated. The parametric modeling method proposed in this paper realized the 3D visualization of lens of the China virtual eye. It provides an available base for the further studies on lens accommodation and surgical simulation research.更多还原
