Nice to hear there is someone using osgSWIG!
I' m using it along with wxpython mainly under Windows.
As a devel environment we are using SPE
If you like, I attach a wxosgviewer contributed by Silvano, a collegue
of mine, our wxwindows expert.
I' m using it also embedded into frames of a wxpython app.
We have a Linux-python savvy, try to run under ubuntu, he managed to run
after som twiddling of the swig - generated .py files.
He was able to run the examples but he got performance problems with
this wxosgviewer using wxpython-gtk.
I' ve not an osg-python-swig linux env to test on, so not able to dig
further
Apart from that, I' m currrently using my patched osgSWIG under winxp
with not many problems.
Thanks in advance, hoping to help

Hi Luigi,
thanks for the patch, I will skim through it ASAP. I was just catching
up with all my local osgSWIG patches - I will add a cleaner wxWidgets
example (the one in the example/python folder was outdated) - based on
osgViewer rather than osgUtil::SceneView.
I got everything working on Windows XP, Linux (Ubuntu 8.04 x86_64) and
Leopard. Can you submit specific problems you have to the osgSWIG
issue tracker?
Cheers,
Hartmut

Hi Harmut, I did not know you were still working on osgswig, If it
can help, I attach some mods we have done to develop some code based
on osgswig
We have tried to add wrapping to write node visitor derived python
I include all our mods, (we have also mod cmake to covert .dll to pyd)
It is tested under win XP with osg 2.5
We have also tried it under Linux and it compiles correctly but has
some runtime problems
We have also integrated osg window with wxpython, it is working under
windows but bad performance under linux
I attach a patch built with tortoise patch
Hope it helps

Nope we are around and kicking. Unfortunately nothing to show yet: I
am working on getting most of the nested classes integrated.

Hi all,
Does anyone know if osgswig is being maintained anymore? Site on
google code doesn’t seem like it’s being updated anymore.
Has the project moved or is it just dead?
