Jason,
Oh, good. I'm eager to see you implement controur lines this way, because I
think it will be a general solution to the problem of contour lines we
discussed earlier, and it will look as good or better than gnuPlot ever did.
Basically you don't have to calculate the contour line segments themselves;
Jmol just checks for all the pmesh or isosurface triangles and their
intersections with the defined plane. So it's very easy to implement.
Possibly interesting is that the "state" of Jmol thus created actually gives
a listing of the exact intersection segments.
Also, that illustrates another new feature of Jmol 11.9, which is that the
DRAW command now allows drawing of arbitrary line segments in a very simple,
compact syntax:
draw ID line1 lineData [{pt1} {pt2}, {pt3} {pt4}, ... ]
draws line segments from point-pair data
With that in hand, you should be able to do just about anything.
By the way, I REALLY like the way you are using zip files to keep it all
together. That is a great idea.
