Hi,
OK, I managed to achieve a similar behavior by modifying the ReadFileCallback:
[code]
#include <osgViewer/Viewer>
#include <osgDB/Registry>
#include <iostream>
#include <osg/ProxyNode>
class MyReadFileCallback : public osgDB::Registry::ReadFileCallback
{
public:
virtual osgDB::ReaderWriter::ReadResult readNode(const std::string&
fileName, const osgDB::ReaderWriter::Options* options)
{
osgDB::ReaderWriter::ReadResult res =
osgDB::Registry::instance()->readNodeImplementation(fileName,options);
if(res.notFound() || res.notHandled() || res.error())
{
OSG_WARN << "DatabasePager could not load file, stopped trying: " <<
fileName << std::endl;
osgDB::ReaderWriter::ReadResult notfound(new osg::Node(),
osgDB::ReaderWriter::ReadResult::FILE_LOADED);
notfound.getNode()->setName("Not found");
return notfound;
}
return res;
}
};
int main(int argc, char ** argv)
{
osgDB::Registry::instance()->setReadFileCallback(new MyReadFileCallback());
osg::ProxyNode* proxynode = new osg::ProxyNode();
proxynode->setFileName(0, "NOTFOUND.ive");
osg::ArgumentParser arguments(&argc,argv);
osgViewer::Viewer viewer(arguments);
viewer.setSceneData(proxynode);
return viewer.run();
}
[/code]
This increases my framerate a little because I have a faulty model that kept
spamming the database pager with file not found-caused reloads.
I still think that it would make sense to treat local file not founds a little
different than the current way. I stumbled on the reload issue by chance when I
implemented a ReadFileCallback, my application did constant reloading all the
time without me noticing!
Thank you!
Cheers,
Martin
