Summary: Calculation and display of various surface types

Initial Comment:
In order to establish Jmol as a Chime replacement, the
calculation and display of various surface types would
be needed. 
The attached graphics have been take from teaching
module of the german project "Networked chemistry
studies" which is currently based on Chime but where at
least some people would love to get rid of it.

The file names "Chime Gasteiger charges" shows a model
calculated by the following chime command:


script="surface molsurface white 0.45; list molsurface
transparent; set 
mep distance 99.0; set charge function gasteiger;
calculate charges 
refresh; list molsurface color potential"

The other one named "Gaussian cubs" has been created
from a so-called cubs file produces by the
ab-inito-program Gaussian. The cubs file is also attached.

It would be nice if user could retrieve numbers from the
console  that are similar to the .rsa and .asa files
produced by naccess.  

Questions:

1) Do you intend to use the cdk implementation?
http://cdk.cvs.sourceforge.net/cdk/cdk/src/org/openscience/cdk/geometry/surface/NumericalSurface.java?revision=1.13&view=markup

2) Any updates on when this might be available?

Adding surfaces is certainly a priority. 

However, support for surfaces will come after the official
v10 release

I would like to see this a priority. Descriptions of the
functions can be found at

http://bip.weizmann.ac.il/course/prog2/graphics/chimescript2.html#set_mep_mlp_function

At the very least we should have something like:

surface molsurface white 0.1;
set mep distance 100.0;
set charge function gasteiger; 
calculate charges refresh;
list molsurface color potential red orange yellow green blue
darkblue;
list molsurface transparent;

"mep" here stands for "molecular Electrostatic Potential"

These are very useful. But I have found that Chime does a
poor job of rendering the colors. We could do much better.
