Dear Robert,
Thank for your answer. One more question. Right now I have my code like this:
numOfFrame = 0;
startTime = time(NULL);
while (!viewer.done())
{
viewer.frame();
numOfFrame ++;
}
endTime = time(NULL);
frameRate = (double)numOfFrame/(endTime - startTime);
But it always gives me about 60fps. Did I make a mistake somehow?
(startTime and endTime are in seconds already)
Thanks,
Dat
