Hi all,
I have a project where I will be drawing nothing more than simple
circles with lines connecting them. At some point, I will be animating
these lines and circles to move them to another position.
I would like to:
(1) Display these, animated, on the screen; and
(2) Render the animation to a QuickTime file.
As far as the lines themselves go, a multi-layered CALayer (using
CALayer's -addSublayer method) would work perfectly for viewing on the
screen... but I don't know how to export this to QT.
So, I have two questions:
(1) Is there a way for me to create the animations with CoreAnimation
Layers (CALayer and sublayers) and simply tell some object to write to
file? If so, how?
(2) What is another method to create the animation easily? I would
prefer that the same code be used to both display on screen and render
to file; but it would also be acceptable to write to file then play
the file on screen.
Note that I am going more for simplicity of code rather than speed
performance, as the on-screen viewing will ONLY be for 'previewing'
the output. All "publications" of the animations will be in the form
of a QuickTime video.
