[x3d-public] HAnim only skeleton renderable ?

[Leonard Daly]

Andreas,

This does not directly answer your question.

In character animation the skeleton created during the rigging process 
is never rendered. It is a collection of points in space that the skin 
is anchored to. During development and animation, the skeleton may be 
rendered by the animation and/or rigging tool; but geometry is never 
created for it. Of course an author may choose to create a mesh for the 
skeleton, in which case it would be rendered as regular geometry.
