I try to explain better my problem...I've written a simple file defining
only one visitor, which change the filename associated with the first child
of every pagedLOD in the scenegraph... I test it on a model that contain
some pagedlod (exampleModel.osg) but the visitor has no effect.... can
someone explain me the reason of this fact ?
the file I've written is:
#include <osg/Notify>
#include <osgDB/ReadFile>
#include <osgDB/WriteFile>
class ProvaVisitor : public osg::NodeVisitor
{
public:
ProvaVisitor():
osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN)
{
}
virtual void apply(osg::PagedLOD& plod)
{
plod.setFileName(0,"a");
}
};
int main( int argc, char **argv )
{
osg::notify(osg::NOTICE)<<"Charging the model...";
osg::ref_ptr<osg::Node> root = osgDB::readNodeFile("exampleModel.osg");
osg::notify(osg::NOTICE)<<"Done"<< std::endl;
ProvaVisitor v;
root->accept(v);
return 0;
}
thanks

Subject: [osg-users] PagedLOD...problem with setFileName() method
Date: Thu, 05 Oct 2006 17:41:16 +0000
Hello everybody,
I need to define a visitor which, in certain case, have to change the file
referred to some children of pagedLOD nodes in the scenegraph...so in my
visitor I define an apply() method for pagedLOD in which body I made a call
of setFileName() method...
virtual void apply(osg::PagedLOD& plod)
{
...................
plod.setFileName(i,sameFile);
...................
}
where "i" is an integer and "sameFile" is a std::string...
after the visitor's traverse there is no change in the name of the file
associated with the child in question...what I wrong ?
Thanks in advance
Leo
