The property of B-Spline is to modify only partial curve rather than the whole curve, i.e. if additional points
between 2 Master positions are inserted, only the curve in the section is modified, and the curve besides the
section remains in the same shape. Here is the example of inserting 210, 250, and 290 between Master position
200 and 300. We can observe the curve variation of each point.
The above example illustrates the horizontal variation of inserting different Master positions. Here is another
example explaining the vertical variation of inserting differenct Slave positions1, 5, 10 and 15.
