[chimera-dev] Different models

[Thomas Goddard]

Hi Marco,

   The Chimera volume path tracer tool has some similarity to your 
proposed Chimera tool.  It allows you to place markers on volume data 
and connect them up.  The markers could represent molecules, domains, 
... and are implemented as a Chimera molecule, so all the coloring, 
selecting, hiding/displaying capabilities of molecules are available to 
the user.

   The volume path tool is implemented all in Python in directory

	chimera/share/VolumePath

Look specifically at the markerset.py file which defines classes 
Marker_Set, Marker, and Link that are wrappers for Chimera Molecule, 
Atom and Bond.
