And you might have similar problems i had, so here is the current state:
Fortunatly i can tell you that all my problems are solved by now ;).
Unfortunatly, for that, i have made a complete rewriting of the code!
And i'm still stuck with guesses what could have happened (read the old
mails),
that in fact is one of the things i hate, cause there is still this
little
uncertainty in the back corner of my head, you might know that ;)
feeling.
Anyway, it runs ok,
but during the whole process some questions about Performers C++ API
arose
too, in first tries to use Performer, most people will use a copy and
paste
solution from examples in pguide etc (most C API). That is how my app
started back 3 years from
now. But after a while you might experience more and more that the
complexity of your programs will not work in any case with that simple
solution.
The OO paradigme seems a good way to come around it. And Performer
supports
it with it generic C++ API.
But what is painfull is that there is only one chapter in the pguide
about
how to subclass pf-nodes, what is in fact the first thing that comes to
ones mind. But to really unleash the object-oriented power you really
want
more, well i did at least. And to get more, basically you can try and
error
subclassing anything else, most of the time not beeing shure if this was
the easiest
way to solve a given problem.
Maybe here are more people that want to share their ideas and solutions
on C++ program design on a problem based basis? To name just a few i was
dealing with:
- How to implement specific object features, animated nodes, kinds of
animation and more
- How to implement a generic view class that supports all kinds of
stereo.
- How to have abstract classes that encapsulate different projection
medias
(HMD,s big screen's, and more)
- How to achieve online switching between different view models
- ...you name it...
If this will be done in an open discussion, i think lots of people will
think: " oops, thats a good idea, i should have done that"
in contrast to try and error ;)
what do you think?
