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.

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.
