[chimera-dev] adding an exporter

[Tom Goddard]

Hi Matt,

  The registration for the Collada exporter is in the file

	chimera/share/ExportCollada/ChimeraExtension.py

	http://plato.cgl.ucsf.edu/trac/chimera/browser/trunk/libs/ExportCollada/ChimeraExtension.py

The ChimeraExtension.py file for each Chimera extension is imported when Chimera starts.  I believe that is all that is needed to have the format appear in the File / Export Scene… menu.  I don’t know how you intend to get extra input parameters for exporting Blender Collada.  None of the Chimera export formats take extra input parameters.  So the Export Scene… user interface just presents a file save dialog.  If you need some other GUI the easiest approach is not to use File / Export Scene….  Instead make your own “Export Blender Collada” in the Tools / Utilities menu.  To see how to do that look at some other example Chimera extension that has a Tools menu entry, like the Icosahedron tool
