Seamless3d displayed the exact positions of the pivot points you specified in your 'joint centers'.
To show one of your mistakes, I copied directly from your original code here:
DEF Joe_vl1 HAnimJoint { name "vl1" center 0.0 1.1459 -0.0625 skinCoordIndex [ ] skinCoordWeight [ ]children [
DEF Joe_vt12 HAnimJoint { name "vt12" center 0.0 1.179 -0.068 skinCoordIndex [ ] skinCoordWeight [ ] children [
DEF Joe_vt11 HAnimJoint { name "vt11" center 0.0 1.2679 -0.0810 skinCoordIndex [ ] skinCoordWeight [ ] children [
DEF Joe_vt10 HAnimJoint { name "vt10" center 0.0 1.242 -0.09 skinCoordIndex [ 15 ] skinCoordWeight [ 1 ] children [
and deleted all but the y components for the 'joint centers' and the names of the joints here:
vl1 1.1459
vt12 1.179 greater than previous joint
vt11 1.2679 greater than previous joint
vt10 1.242 less than previous joint
This does not make sense for a human backbone.
You also have pivot points outside of the skin.
You also have a vertex in each hand that overlaps an adjacent triangle edge.
These are the sorts of mistakes humans easily make when using a text editor with limited graphical verification to show what they are doing.
