一种视相关的网格简化方法

A View-dependent Mesh Simplification Method

针对网格模型的实时显示问题提出了一种视相关的网格简化方法。在网格简化中,将影响图形对象重要性的视觉敏感度与图形对象在屏幕上投影面积两者有效结合,实现网格模型的实时大幅度简化,实验结果表明,简化速度快,但显示并无明显失真。

Aiming at the real-time display of mesh model,a new view-dependent mesh simplification method is proposed, which combining the visual acuteness and projection area of graphic objects on the screen ： two factors which affect the importance of graphic objects：in mesh simplification. The real-tlme drastic simplification of mesh model is achieved. The result of experiment shows that the speed of simplification is fast,however, the fidelity can be kept perfectly.
