The joint matrices are described here with this pseudocode:
jointMatrix(j) =
globalTransformOfNodeThatTheMeshIsAttachedTo^-1 *
globalTransformOfJointNode(j) *
inverseBindMatrixForJoint(j);
The "inverseBindMatrix" comes from the glTF model skin definition.
A complete working example is included with the glTF Sample Viewer, here:
https://github.com/KhronosGroup/glTF-Sample-Viewer
In particular, src/skin.js
might be what you're looking for.
