Hi David, VRML support in Chimera is quite limited and the surface color tool which works on all other Chimera surfaces does not work on VRML. If you are calculating the custom surfaces described as a set of vertices and triangles then I can provide some Python code that will make a surface that you can use the surface color tool on. Here's some documentation on what that Python code would look like: http://www.cgl.ucsf.edu/chimera/current/docs/ProgrammersGuide/Reference/surf... If you are generating VRML with some software you did not write it still may not be too hard to extract the vrml indexed face set node describing the surface and generate the surface as above with a bit of Python.

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: http://www.cgl.ucsf.edu/chimera/tutorials/volumetour/volumetour.html#icossur... except that I want to use custom geometries....
Many thanks, Dave
