Examples of the Stiffness parameters

In this example, using the GSM command, we modified the curve, preserving its endpoint P on the left and moving its point Q to match the isolated point Q' on the right.



The different results were obtained with different stiffness values (1, 2, 40).
 
X stiffness: 1
Y stiffness: 1
Z stiffness: 1
X stiffness: 2
Y stiffness: 2
Z stiffness: 2
X stiffness: 40
Y stiffness: 40
Z stiffness: 40

In this example, the point on the blu line must match the point on the red line:



See below what happens when you vary the stiffness values:
 
X stiffness: 4
Y stiffness: 4
Z stiffness: 4
X stiffness: 2
Y stiffness: 2
Z stiffness: 2
X stiffness: 1
Y stiffness: 1
Z stiffness: 1
