ok, that's in. I'll upload a version later this morning. These can be saved as JVXL files with a space savings of about 75%.

use the OBJ keyword prior to the file name:

isosurface OBJ "sample.obj"

See attached image. Note that these can be mapped with values from another function, just like "isosurface PMESH".

Eran,

I see the format described at http://www.eg-models.de/formats/Format_Obj.html
It's almost a pmesh file. It would be simple enough to get Jmol to read that format using the isosurface PMESH or just the pmesh command itself. We might have to ignore a few things (texture, normals, larger polygons.

Have an example file I can play with?

I see.

Jmol can export 3D object files such as VRML -- can it read any of these files as well?  (I'm thinking that maybe I can convert my Wavefront object file into one of these filetypes and then load it into Jmol, if possible)

Hi Bob,

In our case it's a Wavefront object file.

"obj" could be anything. What is it?

Electron density: I've worked out a preliminary version of electron density plotting and mapping in Jmol. It's pretty slow, because all of the occupied MOs have to be scanned. But it does work.... at least for RHF. I have it ignoring d and f orbitals.

Thanks Bob!

Another question for anyone who may know:

I have a .obj file that I would like to visualize in Jmol. Is anyone aware of a way to do this (possibly by first converting it to a different format that Jmol can read)?

Thanks for the help.

Eran


I for one would like to display isodensity surfaces for wave
functions calculated with the GAMESS-US program.
