Hi all,
after some further testing, I have found some problem regarding loading of
OSB files. Please see attached code sample (modified testVRMLLoader.cpp) and
correct me if I`m wrong, but it seems that that loading time of OSB after
previously deleting nodes is much higher. Difference can be seen also on
relatively small files. Is there something wrong in sample code attached?
Kind regards,
Robert
#include "OSGSceneFileHandler.h"
#include "OSGFieldContainerFactory.h"
#include "OSGTime.h"
int main (int argc, char **argv)
{
OSG::osgInit(argc,argv);
OSG::NodeRecPtr file;
std::vector<OSG::NodeRecPtr> vFile;
if(argc > 1)
{
//first round
for(OSG::UInt32 i = 0; i < 2; ++i)
{
OSG::Time start = OSG::getSystemTime();
file = OSG::SceneFileHandler::the()->read(argv[1], NULL);
vFile.push_back(file);
OSG::commitChanges();
file = NULL;
OSG::Time end = OSG::getSystemTime();
std::cerr << "Took " << end-start << " seconds to load" << std::endl;
}
OSG::commitChanges();
for(OSG::UInt32 i = 0; i < vFile.size(); ++i)
{
vFile[i] = NULL;
}
vFile.clear();
OSG::commitChanges();
//second round
for(OSG::UInt32 i = 0; i < 2; ++i)
{
OSG::Time start = OSG::getSystemTime();
file = OSG::SceneFileHandler::the()->read(argv[1], NULL);
vFile.push_back(file);
OSG::commitChanges();
file = NULL;
OSG::Time end = OSG::getSystemTime();
std::cerr << "Took " << end-start << " seconds to load" << std::endl;
}
OSG::commitChanges();
for(OSG::UInt32 i = 0; i < vFile.size(); ++i)
{
vFile[i] = NULL;
}
vFile.clear();
OSG::commitChanges();
}
OSG::osgExit();
}
