I am looking at some rather noisy cryo-tomography data and I would like to create something akin to icosahedral and spherical sections, using different shapes (cylinders, ellipses etc). I have found spherical and icosahedral sectioning to be a valuable way to represent density and would like to use this in other types of structure. Is it possible to colour the surface of an imported VRML object in the same way as spheres and icosahedra are in the tools>volume data>surface colour dialogue? In my current chimera installation, VRML objects are not listed in this window....

The sort of effect I want to achieve is similar to that described here:

except that I want to use custom geometries....

Many thanks,

Dave
