Hi Rick,
You can call addFileExtensionAlias() within your own program. I would
recommend doing that instead of modifying the OSG source. I've written a
plugin that handles multiple extensions, so I use this technique
successfully within my OSG app. Here is the code you would insert into your
application:
osgDB::Registry::instance()->addFileExtensionAlias("csg", "nsm");
If you are creating your own application that uses the plugin, then I don't
see a problem with this solution.
However, if you are trying to add support for these extensions to a 3rd
party application, then this solution won't work. In this case, I would
suggest creating a separate plugin called osgdb_csg.dll that forwards the
loading to the original osgdb_nsm.dll plugin, therefore avoiding duplicating
the code in two different files.
Cheers,
Farshid
