| 摘 要： | 由于计算机在处理大规模三维网格的过程中会出现严重的延迟,影响场景显示的视觉效果,主要研究了以视觉效果为首要条件的三维网格模型简化方法及QEM算法。首先,对网格简化方法进行了分类;其次,给出了网格简化的误差评判方法;最后,基于OpenGL,采用顶点对收缩方法,并结合QEM算法进行了实现。模型简化了93.7%时,仅用时111.78 ms,同时保证了输出网格的视觉效果。

| Abstract: | The computer may cause the serious delay when it processes the large 3D mesh, which influences the visual effect of the scene. Taking the visual effect as the primary condition, the simplification method of 3D mesh model and QEM method are studied. Firstly the simplification methods are classified. Then the error evaluation methods of the simplification mesh are studied. Finally the QEM method is implemented based on OpenGL. It only takes 111.78 ms to accomplish 93.7% of the simplification, meanwhile the visual effect is also remained. |
