Hello all, As part of a project that I am working on, I recently wrote an extension for Chimera that exports the scene as a .vtk file which can be read into the Visualization Toolkit <http://www.vtk.org> or Paraview<http://www.paraview.org>. It exports atoms (points), bonds (lines) and surfaces along with other data associated with them such as the atom and residue names, residue number, position along its chain, b-factor, occupancy, etc. in a format that can be used in VTK-based applications with the default file readers. I think this could be a good thing to add to Chimera itself, so I was wondering if you would like to have the code for the extension to add to Chimera itself. I look forward to hearing from you, -- Shawn Waldon Graduate Research Assistant Department of Computer Science University of North Carolina at Chapel Hill swaldon@cs.unc.edu
