FreePosture model scaling

Main Forum

I found that the FreePosture model uses ScalingStandard.any to set the fiber lengths. However in the AnyFolder FiberLengthScaling of the ScalingStandard.any file, are these scaling factors?

AnyFolder FiberLengthScaling = {

AnyFolder Pelvis = { AnyVar FiberLengthScale = 1.0; };

AnyFolder Right =
{
  AnyFolder Shank = { [b]AnyVar FiberLengthScale = 1.0;[/b] };
  AnyFolder Thigh = { AnyVar FiberLengthScale = 1.0; };
  AnyFolder Foot  = { AnyVar StrengthScale = 1.0; };         
};
AnyFolder Left =
{
  AnyFolder Shank = { AnyVar FiberLengthScale = 1.0; };
  AnyFolder Thigh = { AnyVar FiberLengthScale = 1.0; };
  AnyFolder Foot  = { AnyVar StrengthScale = 1.0; };         
};

};

Where would I find the actual fiber lengths as opposed to the scaling factors? I've been looking throughout the model directory of FreePosture to no avail.

EDIT: Is this located in StandardParameters.any?
For example:

AnyFolder Head ={
AnyVar Mass = 0.081*.BodyParameters.BodyMass; //C7-T1 to ear canal
AnyVar Height = 0.14;
};

Does this mean that the head is 0.14 metres in length?

Kind regards,

Jared

Hi Jared,

Please have a look at the muscle model tutorial this will give you some background knowlegde. see eg http://www.anybodytech.com/fileadmin/AnyBody/Docs/Tutorials/chap5_Muscle_modeling/lesson5.html

About the head height i belive this is measured from the last cervical joint to the top of the head.

Best regards
