Hello Frank,
However, I haven't the faintest idea of what I'm doing and why I'm
doing the things I'm doing. I can copy code, change a few file/path
strings, even add some drawables to a scene and view the new scene in
the basic viewer (following the tutorials) and it all looks really
pretty. But, I feel at a loss when I try to use the osgviewerWX
example in my own project because it doesn't work as I expect it to
and haven't got a clue why. It's probably because I forget something
very basic, but I don't know that the basic thing needs to be done.
Well, if you have all that information I can't see why you would be
struggling with basic concepts...
I think that it's probably due to the fact that I'm fairly new at this
whole game. I simply can't read code and understand why the code is
there. Why, for instance, is there a GraphicsWindow and a
GraphicsContext? What does the Viewer do and why do I need to call
setGraphicsContext? Ok, from the code it's apparent that I should, but I
haven't the faintest idea why. Reading the wiki or the doxygen
documentation just doesn't provide me with that information.
In short, again, I would like to know the theory, the design principles,
etc. Is there such documentation available?
If you explain what your problems with osgviewerWX are, perhaps someone
who knows it well on this list can help you. You assume it's something
basic, but we can't know unless you give us more information. What are
the symptoms you're seeing?
In the meanwhile I've been able to get things working. Not in the way I
would like everything to work, but I at least have a working canvas for
OSG to render on.
What went wrong was that the code which was generated by wxGlade, which
I used for building a simple GUI, simply didn't cooperate with the
example code provided with OSG. It's quite a long story, but all in all
and for the moment I'm a happy camper. I expect things to break apart
again rapidly though, as soon as I try and implement something else. ;)
Partly because I still only have but a slight understanding of what's
happening under the hood.
In any case, thanks for the pointers.
Frank
