摘    要:网格简化是科学计算可视化和虚拟现实领域中的一个重要研究方面,它在不严重损失物体的视觉特征的前提下,用较少数目的多边来表示物体,减少了模型的复杂性,提高了绘制的速度,文中提出了一个适合于表面曲率变化不太大的网络简化算法。

关 键 词:网格简化  表面简化  细节层次  虚拟现实

Abstract:Mesh simplification is a very important aspect in the virtual reality and scientific visualization. It uses fewer polygons to represent the model of object without significant loss in the visual characteristics of the object, thus reducing greatly the complexity of the model and achieving higher rendering speed. This paper presents a mesh simplification algorithm suitable for surfaces with lower curvature variation, which using edge collapse to delete edges in coplanar region and merge collinear edges according to the normals of the end vertices of edges. This paper also presents an error metrics based on normal and uses it to guide the simplification.
Keywords:Mesh simplification  surface simplification  level of detail  virtual reality
