Hi,
for redrawing, call function requestRedraw() on View(er) you want to redraw. I
suppose you are changing the scene by yourself.
If you want redraw on demand, other than calling frame by yourself use
osgViewer::Viewerbase::setRunFrameScheme(ON_DEMAND);
In QtViewer example there's QTimer for redrawing, but it calls frame() every
tick. If you want redraw on demand, see fuction osgQt::setViewer() or use this:
Code:
if( viewer->checkNeedToDoFrame() )
{
viewer->frame();
}
Btw. comparing two matrices of doubles has to be done with epsilon delta,
because of precision problems.
Cheers,
Filip
