Hi Robert,
Do you know how to test the osgViewer is using ON_DEMAND flag? Here is my
code:
void cOSG::Render(void* ptr)
{
cOSG* osg = (cOSG*)ptr;
osgViewer::Viewer* viewer = osg->getViewer();
viewer->run();
}
void cOSG::initOSGViewer()
{
putenv("OSG_RUN_FRAME_SCHEME=ON_DEMAND");
osgViewer::Viewer* osgViewer = new osgViewer::Viewer();
...
...
}
Before I create osgViewer, I added environment variable. But I can't see
any different compare without environment variable setting. I am not sure
whether osg viewer is using ON_DEMAND.
Regards,
Clement

You have the source code, your hopefully are a programmer so should be
capable of looking at the API and reading what the methods are.
Please try it before asking lots of low level questions that could be
answered with a quick look with an editor.
Robert.
