So, RasMol/Chime is right-handed, but it has the +Y axis pointing *down*.no, only the Windows version,
on Irix RasMol2.7.2.1 shows up with true right-handed annotated axis system, but
(Note that we are going to try to keep this relatively simple by not yetthat is a problem,
introducing the issue of rotations about the axes)
though rotation on x and z are as expected, y rotation is not on Irix (but it is in agreement with with the wrong axis annotation in RasWin)
this should be corrected in RasMol and RasWin, too.
What do people think we should do about it?
1. Maintain RasMol/Chime compatibility ... +Y points down
- RasMol/Chime users are used to seeing their molecules
in this orientation
- won't break existing scripts
- nobody really cares, just leave it alone
2. Break RasMol/Chime compatibility ... +Y points up
- this is the way it should have been done in the
first place, we have an opportunity to fix it,
let's not propogate errors
- if someone *really* needs to see their molecules
in the RasMol/Chime orientation they can just do a
'rotate x 180'
I vote for 2 don't pollute the Jmol code with bugs. Regards, Jan
3. Support both - just add a switch/script command to Jmol - it is easy to do ... Jmol already does both - Q: What should the *default* orientation be? - Q: What do you call this switch in a menu? - Q: Any proposal for what the script command should be?
