Re: [Jmol-users] Multiple clipping planes (using slab/depth HKL)

[Robert H. <ha...@st...>]

Well, that wasn't so bad.

isosurface na1 cap unitcell center {atomno=1} sphere 2.0

does what you see there for one of the atoms

isosurface na1 slab unitcell center {atomno=1} sphere 2.0

does that, but doesn't close the ends. Kind of cool that this addition only
about 20 lines of code. Fun!

So the solution is to create a sphere isosurface for each.

Kind of neat that the unitcell doesn't have to be orthogonal.

Also works with boundbox.
