[Chimera-users] Movie for various clipping

Hi Hyeong-Tae,

  I am making a movie now where I show a rectangular indentation in the face of an electron microscopy map, and then the indentation gets gradually deeper tunnelling into the density map.  This is for a planetarium movie which has a very wide field of view so I fly the view point into this rectangular tunnel so you can see the data on all sides.  Making the rectangular indentation is not easy -- I use 9 copies of the same density map, one for each rectangular face of the indentation (5 faces) and 4 rectangular strips to show a hole in the front face of the original map.  Then I move these faces with the volume planes command.

  I'm not sure if the above example is what you have in mind.  Chimera does not have exotic clipping methods -- just planes.  You can use box display mode to show 6 faces of a box within a density map using the Orthoplanes feature (volume dialog menu Features / Orthogonal planes).
