Good.

The current *development* version *does* have a 3D rendering engine.

I recently posted some simple demo pages on the web, but they demonstrate
some of the capabilities:

  http://jmol.sf.net/demo/atoms
  http://jmol.sf.net/demo/bonds
  http://jmol.sf.net/demo/trace

For something a little more complicated take a look at the following. It
is a small application that was auto-converted from chime using the
chime2jmol.pl perl script (which is available in cvs, but is not yet
generally released).

I think (hope) that this will do a better job of impressing the chemists ;-)

The development version of Jmol currently has almost all the capabilities
of the RasMol/Chime scripting language. You can select specific atoms and
change change colors & size, etc.

> adding lines to indicate e.g.  hydrogen bonds,
In what context do you need to 'add' hydrogen bonds?

The RasMol commands for 'monitor' are available and can be used to connect
atoms. If other mechanisms are needed, and they seem to be general
purpose, then I am sure we can fit them it.

> and of course surfaces.
of course *surfaces* is the thing that we do *not* yet have :-)

We have dotted vanderWaals surfaces and dotted Connolly Solvent Accessible
Surfaces, but no true isosurfaces yet.

Yep, well they are still upcoming. But take a look at the prerelease demos
mentioned above and let us know what you think.
