Thanks very much! I have solved this problem by using command replay. My
virtual bender machine is driven by a series of commands. I record how
many steps (store in TotalSteps) are done and when record is required, I
repeat previous steps (TotalSteps-StepBackward) to make every machine
part and pipe a certain position. This process is not shown to users,
the see the last picture.
while(true)
{
DoStep();
TotalSteps++;
viewer.frame();
}
....Keyboard handler when 'b' is pressed, playback.
while(playbackEnd)
{
DoFromFirstStep();
for(int i=0;i<TotalSteps-StepBackward;i++)
{
DoSteps();
}
viewer.frame();
}
This works well. But a problem is, when steps are huge, this playback
will become very slow. This should be optimized in future.

Hi,
You can create an osg::AnimationPath to record the position of the
camrea at each frame, then play this back either by setting the view
matrix per frame from the values derived from the AnimationPath, or
use the osgGA::AnimationPathManipulator for this purpose.
This will just record the camera path, not the rest of the actions in
the scene, for the rest of the actions there is record nor mean or
creating a record of what you do to the scene graph, you'll have to
record this some how.

My application is a tube bender simulation application. Now we have a
feature which can record and playback the whole scene, like some car
racing video games. I don't know if OSG have this features and don't
know which directions I should follow, can someone give me a advice?
Thanks very much!
