Hi,
I am trying use the detailed hand model for a problem. I have not problem with the kinematics: I can drive each of the finger joints. However, I cannot put a reference node on a finger segment.
For example, I can easily put a reference note on a thigh segment by:
AnySeg& Ref_Right_Thigh= Main.HumanModel.BodyModel.Right.Leg.Seg.Thigh;
Ref_Right_Thigh={
AnyRefNode KneeMarker = {
sRel = .Scale( {0.09, -0.4, 0.03});
AnyDrawNode drw={
ScaleXYZ={0.01,0.01,0.01};
RGB={1,0,0};
};
};
};
However, I cannot use the same method to put a reference node on a finger segment. I got an error message by using:
AnySeg& Ref_Right_Hand_Finger1_DIS= Main.HumanModel.BodyModel.Right.ShoulderArm.Seg.Hand.Finger1.Seg.DistalPhalanx;
Right_Thumb_DIS={
AnyRefNode Thumb_DIS = {
sRel = .Scale({0.09, -0.4, 0.03});
AnyDrawNode drw={
ScaleXYZ={0.01,0.01,0.01};
RGB={1,0,0};
};
};
};
The finger segments seem not recognized by the system. Is there a bug in the model?
My system: AnyBody V7.1, AMMR.v2.1
Thanks,
John Wu

Hi John,
I think there is a bug in the model code.
You are making a reference to the finger segment called “Ref_Right_Hand_Finger1_DIS”
Then you try to open a different object called “Right_Thumb_DIS”
This will not work it would complain about “Right_Thumb_DIS” so you should write instead if you want to add the node to the distalphalanx
AnySeg& Ref_Right_Hand_Finger1_DIS= Main.HumanModel.BodyModel.Right.ShoulderArm.Seg.Hand.Finger1.Seg.DistalPhalanx;
Ref_Right_Hand_Finger1_DIS=={
AnyRefNode Thumb_DIS = {
sRel = .Scale({0.09, -0.4, 0.03});
AnyDrawNode drw={
ScaleXYZ={0.01,0.01,0.01};
RGB={1,0,0};
};
};
};
Best regards
Søren

Soren,
Thanks for your help. I found an alternative way to resolve my problem. My purpose is to apply a force on the finger segment. Now I simply apply the force to an existing reference marker in the finger segment, what is close enough for my purpose, to avoid making a new reference node.
