Comment (by chapoton):
Little progress.
The problem appears using only the pmesh files and not the script. So the
problem is in the pmesh files.
1) it seems that Jmol does not like the color 0 at all. Replacing 0 by 1
enhances things a little bit. This is a symptomatic cure of only part of
the problem.
2) but the example of comment:115 still does not work
I suspect that there could be some problem inside Jmol about the treatment
of colored pmesh. It may be difficult to investigate without close contact
with the Jmol team.
Here is a new simple testing case
{{{
var('x,y,z')
t = z.function(x,y,z)
cm = colormaps.flag
P = implicit_plot3d(z-x*x-y*y,(x,-2,2),(y,-2,2),(z,-1,4),color=(t,cm))
}}}
Was not working with Jmol
Now works correctly with Jmol
Produces spectacular unexpected special effects with Jsmol
