point of curve meaning in English

弹道起点
曲线起点

The characteristic points of curve are generalized to the characteristic blocks of image based on the studied of curves
在对曲线研究的基础上，将曲线的特征点推广到图象的特征块。
In the existing curves and surfaces formulations , a shape is designed by moving the control points of curves or surfaces
摘要在现有的曲线曲面设计中，曲线曲面的形状是通过控制顶点或数据点来确定的。
The thesis tells surface analysis method including curvature analysis and curve depth analysis that we using in the skin restoring project . in chapter 2 , it tells the definition of b - spline curve and surface and the fundamental algorithm - de boor algorithm for points of curve and surface . as to reconstruct surface from ct data , we discuss some basic algorithm and introduce the wrapping skin algorithm
在第二章中，介绍了b样条曲线曲面的定义及基本算法- -求曲线曲面点的德布尔算法；基于ct数据的曲面重构，讨论了重构过程中所应用到的基本算法(如节点插入及消去算法、曲线的反算方法等) ，并介绍了曲面重构中常用的蒙皮法。
