Robert,
thanks for the comment, however it does not work. Do I need to
extend/patch OSG?
An investigation showed that many plugins check once again in readNode
method whether the extension is accepted. At this moment, ivx is
refused. I am not sure, but the explicit alias that user makes should be
stronger than what plugin thinks about itself. Reasons: Sometimes,
software developers just decide to change file extension while the
format stays the same. The application for interiors design may want to
use "int" extension while file format is still osg, or whatever. I
think, OSG should allow to do that.
Ideas?
I suggest to change
bool ReaderWriter::acceptsExtension(const std::string& extension) const;
to accept even the extensions added by:
osgDB::Registry::instance()->addFileExtensionAlias(from,to);
Comments?
Thx,
John

Question: Is is possible to register the ivx alias?
You have two options, to preload your plugin so it gets tried before
any other plugin so can intercept and handle all .iv file reads, or to
use an osgDB::Registry file extension alias. The later is probably
the neatest solution can be done via:
osgDB::Registry::instance()->addFileExtensionAlias("iv","ivx");
