摘要
引入能量函数的概念,提出了用于Catmull clark细分曲面N边空洞填充的新方法———能量法。该方法以物理变形模型为基础,利用能量法计算未知点填充N边孔洞。填充后的曲面不仅保持了原来的曲面特征,而且达到了二阶连续,更具有实用价值。文中详细地介绍了该方法的基本思想和实现方法,并且给出了应用实例。
A new algorithm is presented for filling n-sided holes in Catmull-clark subdivision surface. This method is based on physical deformation model, and uses energy function to compute the control points. The filled surface not only keeps original feature, but also gets G^2-continuous with exception of one extraordinary point.The basic idea and procedure are introduced in detail in the paper, and some figures generated by the method are presented.
