Yes, I completely agree, the fragmentation is very annoying, but given that
WebGL only came out of beta status last year, I am not surprised.
What I recommend is a grouping of technologies, so Jmol and ChemDoodle should
be used together to reach all devices. Older graphics cards are less likely to
support WebGL (>5 years old, this is because there are no security features
built in to stop abuse on these cards, and on the web, that can be a very
common thing, given that one could never access the graphics card via the web
before) and newer platforms are less likely to support Java, so together I
think there is the most coverage.
Of course, as development continues, WebGL and Javascript will continue to get
faster, graphics cards will be handled and removed from blacklists, WebGL will
appear in more browsers on more machines, and ChemDoodle will have more and
more features. We saw a similar thing with Java, back when it was unveiled, it
was slower, but today, Java performance is very good and no one complains about
it.
Additionally, the meshes used in our PDB demo are very high quality, and for
much larger structures, the quality can be toned down to improve performance.
