[Chimera-users] imod model viewing

[William Jeffrey Triffo]

This brings up a related question,

has anyone written a script to parse out IMOD model files for this 
information (point locations, and their connectivity for contours, 
followed by surfaces)?

My understanding is that the mesh representation is an output format 
that is derived from the actual model data (above) that chimera does not 
currently import.
