OK so I ended up taking osgviewer application and modified the last line from:
Code:
return viewer.run();
to:
Code:
double simTime = 0.0;
while( !viewer.done() )
{
//fire off the cull and draw traversals of the scene.
viewer.frame(simTime);
printf("%f\n",viewer.getFrameStamp()->getSimulationTime());
simTime+=1.0;
}
I then run my modified osgviewer as so:
Code:
osgviewer -p saved_animation.path demo1.earth
with my saved_animation.path containing(only area of concern are the first
numbers of each line, the rest are coordinates,etc):
Code:
0 -2325407.84602605 -3773744.01822793 4620950.6465483 0.789763463262851
-0.198065735037136 -0.0367132622717805 0.579392589763306
30 -2265729.64421162 -3667179.98272433 4731436.64144345 0.782981051316165
-0.194916972743774 -0.0398361681693882 0.589373503579705
But the animation still takes 30 *realtime* seconds to complete, and does so in
370 frames. here is my output:
Code:
....
366.000000
367.000000
368.000000
369.000000
AnimatonPath completed in 30.0006 seconds, completing 370 frames,
average frame rate = 12.3331
Now with 12fps, I would expect the animation path to complete in 30frames
/12fps = 2.5 seconds, while completing only 30 frames.
