Hi,
I have now looked at createStoryBoard_2() from Paive, and have converted into
the
format that I would expect it to look in the current StoryBoard format in the
Spec.
Well, partially converted it - StoryBoard_2 is a fairly complicated example
with a lot of
overlapping transitions, and hence leads to quite a few scenes. I have written
a rough
translation of the first couple of scenes, and just comments for what heappens
in the
remaining scenes.
So that you understand how I have broken up, essentially a scene should contain
a single
effect tree that describes only what is currenlty going on. As soon as
something occurs
which changes the tree, a new scene is started. The kinds of things that can
cause this
are the start or finish of a particular input file, and the start or end of an
effect.
The indentation looks horrendous :-) But that's mostly because the
<inputs></inputs> tag
doubles the amount of indentation required.
