Hi Robert,
thanks, it works now both for distant & local file (using ReadFileCallback).
I can load file in osgviewer using :
sp3d://host:port/path/toto.ive
instead of
sp3d://host:port/path/toto.ive.sp3d
The code was fine, I was just passing a wrong filename :( but some sessions
in the debugger has given me a better idea of how all this stuff is working :)
I'am now considering the osga 'archive' case.
in virtual ReadResult readFile(ObjectType objectType, const string& sRawUrl,
const Options *options) const
i do the following :
------------------------------------------------------------------------------------------------------------------------
----
if the url includes an archive (for example
sp3d://host:2468/3D/archive.osga/titi.ive)
then
download archive.osga
the archive is now contained in memory in a string stream : tStringStream
ReaderWriter *ptArchiveReader =
Registry::instance()->getReaderWriterForExtension( "osga" ) ;
tReadResult = ptArchiveReader->openArchive( *tStringStream, options ) ;
if ( !tReadResult.validArchive() )
return tReadResult;
osgDB::Archive* ptArchive = tReadResult.getArchive();
osg::ref_ptr<ReaderWriter::Options> options = new ReaderWriter::Options;
options->setDatabasePath(sArchiveName);
// sFileInArchive contains the fileame in the archive (titi.ive)
return ptArchive->readNode(sFileInArchive,options.get());
else
// normal file
... this part is working now
------------------------------------------------------------------------------------------------------------------------
----
The openArchive works but the readNode failed.
The _status member is undefined (it should be READ).
Is it possible to make it works from the stream ?
Any hints appreciated.
Frederic.

Hi Frédéric,
I can't spot any problems with your custom callback, and your doing
things roughly how I'd tackle it, so I can't anything more than to
wish you good luck on tracing things using debugging
statements/debugger.
Robert.
