Create2DSkeleton/AppendBone root problem... 2005-06-14 - By Bradley R. Gabe
Back
Hi Raf-
You'll need a more complete answer with regards to chain building, but
here's a quickie that helps with zeroing transforms for any X3D object you
have a pointer to.
// Create a new SITransformation object
var oTrans = XSIMath.CreateTransform();
// Set your X3D object local kinematics to the transform object
myObj.kinematics.local.transform = oTrans;
What's nice about this technique is that it's only 2 lines of code, and
it's freakin fast! :-)
I'll try to work up a more specific example of what you're doing, if
someone else doesn't beat me to it.

My procedure involves creating the first bone in the chain
using<br><br>
1- Create2DSkeleton command to generate the first bone<br>
2- zero out the root to match a null correctly oriented.<br>
3- zero out the first joint.<br>
3- AppendBone to add additional bones.<br><br>
Unfortunately, every time I use an AppendBone command, it seem to
re-orient the root and throws off the rotation bone values.<br><br>
If anyone has a better procedure for handling chain ganeration, with
zeroing bones ???<br><br>
