[Chimera-users] Showing actual electrostatic potential on surface

Hi Boaz,

   That's a nice idea.  I've put a script surfvalues.py on the Chimera 
Python scripts web page to do that.


If you color a surface with an electrostatic potential using the Surface 
Color dialog (e.g. an APBS potential) then as you move the mouse over 
the surface the potential values used in the coloring will be shown.  By 
default the Surface Color dialog samples the potential 1.4 Angstroms 
from the surface so that is the value reported, not the value exactly at 
the surface point under the mouse.  This would be a nice feature to 
include in Chimera.  But I haven't worked out the details -- like how to 
turn this mouse mode off.
