In order to preserve the detail characteristics in mesh simplification,the discrete curvature of curves is introduced to the method based on quadric error metric(QEM) in this paper.

细节是模型的重要组成部分,而顶点的法向量是描述模型细节的一个重要参数,在网格简化中,为了在保持模型的全局特征的同时也能较好地保持模型的细节,提出了一种采用曲率加权的二次误差作为简化代价的方法,该方法基于二次误差(QEM)简化方法,在代价函数中引入了顶点法向量的变化率,即顶点的离散曲线曲率,从而使得网格简化后模型的细节能够较好地保留。
