Hi, I’m trying to analyze the hand kinematics using a mocap model example.
I modified the mocap model to make the model’s hand to move and I used c3d files.
I tried to MotionAndParameterOptimizationSequence but, i got following error messages.
Failed to resolve kinematic constraints. Newton relaxation too small. (final kin. error = 2.757642E-001)
Constraint no. 252 above error tolerance 0.000001, error = 0.000032.
Constraint no. 253 above error tolerance 0.000001, error = 0.001568.

ERROR(OBJ.MCH.KIN3) : E:/P…s/A…y/A…0/A…3/AMMR/A…n/E…s/M…l/M…l/Kinematics.any(74) : MotionOptimization.InitialConditions : Kinematic analysis failed in time step 0
I tried lots of trials(changed the initial motion, reduced the differences between red and blue markers, change markers set-up like Opt and Weight) but, errors above appeared again and again.
So, I compared fullbody mocap model in example folder and I found that there are at least 2 markers on 1 segment. Is it related to errors above?
thanks for your any replies in advance.
thank you
