Hi Helene
I will try to answer your questions
1 : The Buckle motion is controlled using a combination of joints
these can be found in the JointAndDriver folder of in the Buckle.any
folder, i have copied then in here
///Linear measure from disc1 control point to center of buckle
AnyKinLinear Disc3BuckleTopLin ={
Ref=0;
AnyRefNode &ref1=…Disc3.Disc.DiscSeg.node4;
//ref1={AnyDrawRefFrame drw={RGB={0,0,1};};};
AnyRefFrame &ref2=…Segments.BuckleSeg;
// ref2={AnyDrawRefFrame drw={RGB={0,1,1};};};
//ref1={AnyDrawRefFrame drw={ScaleXYZ={0.1,0.1,0.1};RGB=
{0,0,1};};};
};
AnyKinRotational Disc3BuckleTopRot ={
Ref=0;
AnyRefNode &ref1=..Disc3.Disc.DiscSeg.node4;
//ref1={AnyDrawRefFrame drw={ScaleXYZ={0.1,0.1,0.1};RGB=
{0,0,1};};};
AnyRefFrame &ref2=…Segments.BuckleSeg;
Type=RotVector;
};
AnyKinEqSimpleDriver LinTopDrv={
AnyKinLinear &ref=.Disc3BuckleTopLin;
DriverPos={0,0,0};
DriverVel={0,0,0};
Reaction.Type={Off,Off,Off};
};
AnyKinEqSimpleDriver RotTopDrv={
AnyKinRotational &ref1=.Disc3BuckleTopRot;
MeasureOrganizer={1};
DriverPos={0};
DriverVel={0};
Reaction.Type={Off};
};
AnyKinLinear Disc4BuckleBottomLin ={
Ref=0;
AnyRefNode &ref1=..Disc4.Disc.DiscSeg.node4;
//ref1={AnyDrawRefFrame drw={ScaleXYZ={0.1,0.1,0.1};RGB=
{0,0,1};};};
AnyRefFrame &ref2=…Segments.BuckleSeg.Node5;
};
AnyKinEqSimpleDriver LinBottomDrv={
AnyKinLinear &ref=.Disc4BuckleBottomLin;
DriverPos={0,0};
DriverVel={0,0};
Reaction.Type={Off,Off};
MeasureOrganizer={0,2};
};
So as you can see it is a combination of linear and rotational
drivers.
The artificial pushing muscles are not applied directly thorugh
these joints, they are defined in the BuckelSupport.any file.
2: The height H is measure from a point on pelvis to a point on
thorax it changes with the posture of the model.
The measure below is the one that measure this (it is also from the
JointAndDrivers folder)
///This is a PLine between pelvis and thorax
AnyKinPLine H ={
AnyRefNode &ref1=…PelvisRef.PressureNode;// BuckleNodeRight;
AnyRefNode &ref2=…ThoraxRef.PressureNode;//BuckleNodeRight;
// AnyDrawPLine drw=
{Thickness=0.00375;RGB=Main.DrawSettings.Colors.AnyBodyRed;};
};
3: The buckle geometry should resemble to some extend the fiborus
structure in front of the abdomen. The reason for having the bukle
segment is that that we needed something to connect the different
muscles to, and there are no real segment to be used for that. The
bukle segment is driven to follow as close as possible the real
elastic structure present there. Furthermore it is supported in a
way which should resemble the real support conditions to the elastic
structure as much as possible
I hope this answers your questions, otherwise please write again.
Best regards
