Pythagorean Bezier hodograph curves.
通过引入数论中的 Pythagorean方法,得到了一类具有精确等距线的 B(?)zier曲线,即速端曲线满足Pythagorean条件的B(?)zier曲线,称之为Pythagorean B(?)zier速端曲线(PB曲线)。
A transformation that is most useful in the application of the hodograph method is the inversion transformation.
在速端曲线法的应用中，一种最有用的变换是反演变换。
Points in the physical plane are mapped onto corresponding points in the hodograph plane.
物理平面上的点被映射到速端曲线平面上的对应点。
