Abstract: Based on the 3D scattered points,a method for interpolating new points onto the initial triangles is proposed.This
method establishs initial triangles by the data structures,then,in order to subdivision the initial triangles makes use of the
Bezier surface to generate a new control point,and then does local optimization procedure on the model,finally,sets the
light and material onto the final model.The experiments have proved that the method is feasible and effective.

摘要: 基于给定的一批离散点,提出了在初始的三角网格中插入新的控制点进而对三角网进行细分来重建物体的新算法。具体做法是首先根据点面之间的对应关系,建立相应的数据结构来生成初始的三角网格,再在初始的三角网格中借助Bezier 曲面生成新的插入点,进而对网格进行细分,接着利用对边的细分方法对细分后的三角网进行优化,最后在最终形成的网格上进行光照材质的设定来重建物体。实验证明这种方法可以更好地保留物体的细节,是可行有效的。
