几何算法用来计算三维空间中参数化曲线的特征点的值。这些特征点如下:

u 均分曲线的点;

u 等弦长均分曲线点;

u 计算曲线上指定点和距离的另一点;

GCPnts用来计算常量偏差或常量横坐标值的点。这些算法类有:

u AbscissaPoint:根据曲线上指定点和距离计算出曲线上满足要求的另一个点;

u UniformAbscissa:根据曲线上指定的横坐标计算出一系列的点;

u UniformDeflectionCalculation of a set of points at maximum constant deflection between the curve and the polygon that results from the computed points.

例子:Visualizing a curve.
