These two statements taken together are concerning. We don't want to
penalize the performance for the majority of people (i.e., those with
not up-to-date browsers or computers, but can run java).
Well, is it really a majority?
I suppose it's hard to tell.
http://www.khronos.org/webgl/wiki/Main_Page indicates that IE doesn't
have WebGL, for example. According to the google analytics, about 12.5%
of our visits to sagenb.org over the last 6 months have been with IE,
and about 2-3% or so have used an older version of Firefox that doesn't
support WebGL.
Anyhow, it would be really great to see something less flaky and heavy
than jmol
for teaching purposes (when you can make sure that the right browsers
are used).
I agree (but I would put the blame on java applets, not necesarily jmol
particularly). Testing will show how webgl/canvas support compares to jmol.
