[x3d-public] X3d new version

[John Carlson]

You can change position and normal in a vertex shader, but not
connectivity.   I’m pretty sure that connectivity stays the same, unless
you have a geometry (or tessellation) shader.  If you choose to change
position or  normal in a Script,  you will likely find it slower.   Those
are reasons why subdivision (X3DOM) and quality (SAI) are introduced, to
improve quality.  You should try to see if updating subdivisions in X3DOM
achieves what you want.

There really is no need to modify connectivity, imho, unless you are doing
multi resolution modeling (I’ll let you look that up for yourself).

In other words, changing connectivity would look extremely weird.   Even
morphing keeps connectivity, AFAICT.

Suggestion:   Look up ray tracing, and think about probabilistic ray
tracing.

You shouldn’t leverage non-standard features in an X3D implementation,
because you may find that they will become deprecated and removed.
