Hi Bob,
Thanks for looking at the (lighting) issue. I kind of thought this would be
the case when I saw that (lighting) was defined at the global level. Using
size and translucency probably handles most of my users. My app is StarBiochem
(http://web.mit.edu/star/biochem/). The Version 2 BETA incorporate Jmol. In
Version 1 I used Java3D and I really didn't understand enough about what
Biologists are interested in to create a good user interface. My intended
audience for this app is made up of MIT undergraduate students looking at
StarBiochem the night before the homework is due (I have data). Kind of by
accident I didn't put any access restrictions on any of the STAR apps and we
now have about 10,000 users/year for our suite worldwide.
You and the Jmol collaborators do a great job and Jmol has really helped me
deliver a quality app.
Thanks,
--Chuck

Charles,
A great thing to work on. Thank you. With regard to tying lighting to atom
type, this is a rare occasion when I will say, "sorry, not going to happen" --
the lighting effects are generated at a totally different level than atom
effects. By the time those are applied, Jmol is working at the fundamental
level of bits and pixels, not atoms and bond. I'm not optimistic this would
work.
Of course, there are several forms of color blindness. So I would suggest
experimenting more with color and translucency. You might very well come up
with some "user palettes" that are accessibility options for specific forms of
color blindness.
Bob

I have size and translucency on sliders and that works pretty well. I
think that allowing changes of color might not work very well. In
talking with a few folks who are color blind, it seems like ambient,
diffuse, and some combination of specular values are closer to what
they can detect and can manipulate. Changing colors also changes the
(lighting) values, but in a somewhat unpredictable way.
I tried halos with tertiary coloring, but it didn't seem helpful.
