示例1: startTiming
/// Utility function you call before something you want to time, so that the
/// recorded times will all be consistent using the viewer's time.
void startTiming(osgViewer::Viewer& viewer, const std::string& name)
{
osg::Timer_t tick = osg::Timer::instance()->tick();
double currentTime = osg::Timer::instance()->delta_s(viewer.getStartTick(), tick);
int framenumber = viewer.getFrameStamp()->getFrameNumber();
viewer.getViewerStats()->setAttribute(framenumber, name + " begin", currentTime);
}示例2: endTiming
/// Utility function you call after something you want to time, so that the
/// recorded times will all be consistent using the viewer's time.
void endTiming(osgViewer::Viewer& viewer, const std::string& name)
{
osg::Timer_t tick = osg::Timer::instance()->tick();
double currentTime = osg::Timer::instance()->delta_s(viewer.getStartTick(), tick);
int framenumber = viewer.getFrameStamp()->getFrameNumber();
