[Maya2osg-users] Maya2OSG preview

[Javier T. <jav...@gm...>]

  Hi,

  I have added a new MEL command to the maya2osg plug-in. It is called
"osgpreview" and is a slightly modified version of osgviewer. It
accepts the same command-line parameters as osgviewer with the
addition of "--noautohomeview that prevents the viewer to reset the
camera view matrix to a default one.

  It is used by the "Preview" buttons in the shelf. Now when pushing
any of the two "quick preview" buttons (with or without axes), the
scene should be showed in the osgviewer clone using exactly the same
configuration of the camera in the selected viewport. If no viewport
is selected, a default camera will be used.

  This is also the built-in viewer that should be used when no custom
preview command is supplied. But the preview in the export button is
not working yet. I have to fight with maya2osg_export.mel. One thing I
have seen is that the behavior is different when using "osg" format
than when using "osgt". Also, maya2osg_doExportGUI is called from
maya2osg_doExportGUIAndPreview proc passing the camera file name ¿??
this is the reason that the camera file contained the scene instead of
the camera data (osgViewer object). Peter, can you take a look at it?
Maybe I am missing something, or didn't really understand what you are
doing in this script.

  Btw, pre and post processes are not called yet when using the quick
preview buttons, as they assume that exported file is in the path
defined by maya2osg_filepath, maya2osg_filename and maya2osg_filetype,
and the quick preview script exports the file to the temporary
directory.

  What do you think that should be better: to add a parameter to
pre/postExport commands indicating the filepath of the exported file
or that the previewer change the maya2osg_filepath maya2osg_filename
and maya2osg_filetype? Personally I prefer the first option.

  By the way, this new exportation scheme is for brave people. It
doesn't hesitate in overwriting the exported file without asking  :)
