Re: [Jmol-users] HTML5 and WebGL
Can you imagine the response you would have received even just 5 years ago if you had complained because your phone didn't do Java? I would guess that in another 5 years or so the response will be similar. *** Jeff Hansen Department of Chemistry and Biochemistry DePauw University 602 S.

I fully agree that the JavaScript versions have not catched up with Jmol, and with your speed, they will find it hard to keep up too :) But, the point is that the applet environment is getting dated... not much new developments there... no race between Google, Nokia, Apple, Mozilla Foundation to produce the fastest VM...

[Jmol-users] HTML5 and WebGL
Can someone explain to me how the combination of HTML5 and WebGL is a replacement for Java? Is the idea there that HTML5 somehow (via on-the-fly compiling? via pre-compiled equivalents of Java?) can reach the sort of speeds that people need for molecular graphics? Or is this just a dream? I'm just not finding anything out there that suggests it's any more than JavaScript with a 3D canvas. It's true that it would be nice to have built-in 3D graphics, and I can see how in some limited fashion this could be useful, but there's a lot besides rendering that is done in the process of molecular visualization. Construct an MO? Apply symmetry? By the way, I have played some with the free Molecules app for the iPhone. Someone recently mentioned that as a proof of concept that this can all be done on a phone. However, I'm not so sure. Yes, you can do graphics. Nothing particularly awesome about that. It's processing power for calculation that one needs here. I wonder what the limitations of that really are. How large a molecule has anyone gotten to work on that? Is it just eye-candy? I tried 2x9r (58K atoms), and after it downloaded (2-3 minutes), half way through rendering the app crashed. When I started it again, it was able to finish rendering, but the user response is not usable. Any user interaction takes about 10 seconds to process. This is even though the atoms are simply icosahedra, and bonds are hexagonal cylinders. Mind you, I like my iPhone. It's a great phone. Bob -- Robert M.
