截面曲线 meaning in Chinese

cross section curve
section curve

In this process , steps to calculate section points and curves of the blade are given
在实体建模过程中，给出了叶片截面曲线和点的计算方法。
In chapter 3 , we discuss surface restoring method based on ct data which uses the intersection algorithm between spline curve and radial to resample the section curve , then works out surface controlling point array ; take opengl to display the surface with reality and the lighting , coloring effect
第三章讨论了基于ct数据的曲面重构方法，利用样条曲线与射线的求交算法对截面曲线进行重新采样，并反算曲面控制点阵；在其后的显示过程中，利用opengl实现曲面的真实感显示，包括颜色、光照的变化等。
