[x3d-public] Deformable Skin Animation

Wouldn't a deformable skin/ skinCoord example be like BoxMan.x3d in the HAnim examples?
Or do you mean you're trying to do it without the HAnim nodes, calculating it from scratch?

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.
