Hens,
You probably got some intermediate version there. Maybe even while I was
updating it. There should be no problem now at any of:
http://www.stolaf.edu/people/hansonr/jmol/test/json/pmesh.htm
http://www.stolaf.edu/people/hansonr/jmol/test/json/draw.htm
http://www.stolaf.edu/people/hansonr/jmol/test/json/spin.htm
all of which are just different in the examples they list.
Notice that you can reference points that are not just atoms.
Right now you can refer to any absolute point [x,y,z] or
to atom expressions (atomno=10, atomno=11) would be the midpoint between
these two
or to any previously defined object:
draw line1 150 (atomno=1) (atomno=2);color draw yellow
draw line2 350 [line1] (atomno=3);color draw white
This works perfectly; I expect to expand it some as we discover what we
really want.
Basically what we are designing here is simple access to internal
coordinates. Today I
implemented internal coordinate spinning:
spin [line1] 30
and it actually works! Actually, I can't quite believe it works.
Obviously
rotate [line1] 30
center [line1]
are next. (Honest, Miguel, then I'll quit!)
These are very easy to implement. And I got the frame/animation business
sorted out as well, so that
is ready to go.
Or is that what you intended the scale parameter for?
yes, that's it.
Hens
I'm developing some drawing ideas. See
http://www.stolaf.edu/people/hansonr/jmol/test/json/pmesh.htm
The new command is
draw <anyIdentifier> <optional scale> <atom expression or
xyz-coordinate> <atom expression or xyz-coordinate> <atom expression
or xyz-coordinate> ....
Examples:
draw triangle1 150 (atomno=1) (atomno=14) (atomno=15)
draw line1 120 (atomno=1) (atomno=2)
draw line1 200 (oxygen) (nitrogen)
draw triangle1 400
draw line1 300
draw triangle1;color draw red;
draw line1;color draw blue
Thoughts?
