Hi Paul

Thank you for the information, it is very interesting. I had already seen PV in 
action, but not others. I wonder how much hard work is being duplicated in 
parallel.

I'm quite sure that the better performance is due to WebGL, not to the 
efficiency of the software code.

The old problem with WebGL was lack of support in old machines (graphic 
cards). I guess this is a nearly negligible worry today --though I wonder about 
tablets.

Another big issue is permanence; many programs are "experiments" that 
quickly go dead. I have not experienced this with 3D, but It happened with 
2D molecule drawing, very nice and promising ones stopped being 
developed. See http://biomodel.uah.es/en/DIY/

That is worrisome when trying to choose.

But anyway your comparison is very useful and one could design pages 
offerring altenatives to users, as e.g. RCSB is now doing: PV / JSmol / 
JmolJava

If you don't mind, I'd be happy to add your comparison table to the Jmol 
Wiki, so we can easily find it and keep if updated.

And finally, I wish some of the "expertise" of these programs would entice 
someone to step ahead and grab the task of further implementing WebGL in 
Jmol (I'm not saying Bob Hanson)

Long live Jmol!
