Re: [PyMOL] On APBS, Isomesh generation and export

Hi Fernando,

Can't find any bad english in your email :-)

1: https://en.wikipedia.org/wiki/Marching_cubes

2: To open the isomesh again in PyMOL, I suggest to save a PyMOL session file (.pse). Getting access to the actual geometry is more tricky. There is a script on the PyMOLWiki which can convert isomesh and isosurface objects to CGOs. The script could be a starting point for you to export a custom file. The data is rather simple, just a sequence of vertices and normals.

3: VTK? scikit-image?

Cheers,
  Thomas
