摘要
在口腔修复体计算机辅助设计中,利用B样条曲线逼近修复体STL文件的切片截面轮廓数据,通过改变控制点位置来修改曲线,从而实现口腔修复体的局部修改.
In computer aided design of dental prosthesis, B-spline is used to approximate the data acquired from slicing STL file of dental prosthesis. The spline＇s adjustment is carried out by changing positions of the control points, to achieve the local modification of dental prosthesis.
