Spinning is far more complicated in Jmol 11+ than in earlier versions or
in Chime. In particular, the capability to spin around internal axes
makes spinning very much a characteristic of the model loaded. When I
worked on defining the state of a model, it became clear to me that all
the spinning should be model-specific. If it turns out to be a real
problem, we can look at it again, but this is one place where I just
felt we had to make a change. If I forgot to bring it up in discussion,
that's my mistake. The fix for websites is simple -- just issue the spin
command after the model is loaded.
Perhaps it's my preference showing up here in that I happen to be
particularly annoyed by websites that start models spinning.
Certainly this behavior is open for discussion.
[One of these days I need to write a list of which settings are
persistent / applet-associated / retained across models and which
ones are nonpersistent / model-associated, this always raises doubts
on me]
Yes, this was a BIG issue when I went through and brought all the settings
together in one place. (A few stragglers exist.) If you "show state" you will
now see pretty much all of them. Persistent ones are listed prior to the "load"
command.
They include:
lighting:
background [x000000];
set ambientPercent 45;
set diffusePercent 84;
set specular true;
set specularPercent 22;
set specularPower 40;
set specularExponent 6;
bonding:
set autoBond true;
set forceAutoBond false;
set percentVdwAtom 20;
set bondRadiusMilliAngstroms 150;
set minBondDistance 0.4;
set bondTolerance 0.45;
set defaultLattice {0.0 0.0 0.0};
set allowEmbeddedScripts false;
set defaultLoadScript "";
The next set, listed just after the file load are also persistent; they are
listed after file loading because file loading ITSELF is not dependent upon
them or because they might have been changed since the current file was loaded.
# settings;
set defaultcolorscheme "Jmol";
set showmeasurements true;
set showhydrogens true;
set perspectivedepth false;
color carbon [xff0000];
set axesUnitcell;
Everything else -- orientation (including spinning), colors, sizes, and
visibility of objects and models, labels, and atom selection -- are all cleared
when a file is loaded.
The objective is simply to provide a well-defined reproducible state, which is
now possible in Jmol. Spinning definitely mess that up if it is occuring when a
file loads, because the effect of, say, "rotate x 10" is then dependent upon
exactly how much time it takes to load and render the model and get it
spinning. By resetting spinning, we have a reproducible state upon loading.
Note that spinning is the very LAST operation carried out in a setting of the
state.
One possibility is that in the specific case of applets, if Chime-like spinning
is set prior to any file load, we could carry it over. But that would have to
be a special case.
