I am writing a plugin to handle the "nsm" file type, so my plugin is named

the extension "csg" for exactly the same file type. I would like my plugin to
be
called for the "csg" extension as well.
I call supportsExtension() in the c'tor for both nsm and csg. I also override
acceptsExtension() to handle both csg and nsm. I even made two classes so that
I could
have:
REGISTER_OSGPLUGIN(nsm, ReaderWriterNSM) REGISTER_OSGPLUGIN(csg,
ReaderWriterCSG)
all to no avail. None of it gets called on my "csg" file, but my "nsm" file
works
fine, presumably because of the filename convention. I figure there must be a
way to
do this, since there are the supportsExtension function and virtual
acceptsExtension
functions. What am I missing?
Do you create a library 'osgdb_csg.dll'? This is what OSG is looking for if it encounters
a request for 'model.csg'.
You can preload osgdb_nsm and after that OSG will pick that for .csg files (because of the
'supportsExtension' call). There should be no need for a separate ReaderWriterCSG class
or a separate REGISTER_OSGPLUGIN call.
Cheers,
