Without H-Anim. X3DOM has not implemented H-Anim and that type of
animation needs to be available in there. I used BS Contact because
I didn't want to have to create the entire node structure to develop
and test the algorithm. <br>

Subject: [x3d-public] Deformable Skin Animation
I am trying to construct an example of deformable skin based on joint animation. The example calculates the new vertices for a very simple (and small) object. To work slowly through the process, I started the work in BS Contact. The calculation involves some matrix calculations. These appear to not be available in BS Contact's Script node. I have found problems with
* X3DMatrix4
* X3DMatrix4.setTransform
* X3DMatrix4.multMatrixVec
This is the first time I have tried anything like this -- so I very well may be doing this wrong. If anyone has any references or examples where they did calculations with 4x4 matrices in BS Contact, please let me know.
So far, I have unrolled the calculations and am advancing (aka debugging) the algorithm. I will soon move it into X3DOM.
