[chimera-dev] Colormap surfaces

[Thomas Goddard]

Hi Steve,

  You can make colormapped surfaces from Python.

  You can use TextureColors (see TextureColor.h) with MSMS surfaces.
The chimera/share/DelphiViewer/MSMSTexturer.py code uses this to map
electrostatic potential onto a molecular surface.

  You can also use the _surface Surface_Group.set_vertex_colors()
to color a Surface_Model however you like.  This doesn't use a colormap.
You would just iterate over the surface vertices and calculate colors
for each one.  This was not in Chimera 1700, but is in the Chimera
snapshot I gave you and will be in the next release.

    Tom
