Re: [osg-users] ANN: osgSWIG/Py available
Hi,
I'm trying to run the gtkoswidget.py example in python IDLE 1.2.1 and I got
stuck at gtk:
import sys
import pygtk
pygtk.require('2.0')
import gtk
Traceback (most recent call last):
File pyshell#3, line 1, in module
import gtk
File C:\Python25\lib\site-packages\gtk-2.0\gtk\__init__.py, line 38, in
module
import gobject as _gobject
File C:\Python25\lib\site-packages\gtk-2.0\gobject\__init__.py, line 30, in
module
from _gobject import *
ImportError: DLL load failed: The specified module could not be found.
Can someone tell me how I can fix this or where I can get a working gtk version?
Thank you,
Linh

Dear OSG Community,
first of all a late Happy New Year! The osgSWIG team is happy to announce
osgSWIG/Py 0.9.1 for Python 2.6 which corresponds to the OpenSceneGraph 2.6.1
version. There is an installer for Win32/Python 2.6 or if you feel funky you
can try to compile osgSWIG/Py straight from the source.
Please note that on Windows we can only support you with Python 2.6 - hence
build with Visual Studio 2008. And another note, we decided to only support
stable releases, like 2.6.x or the upcoming 2.8.x releases as the maintenance
of the interface files becomes more problematic. Be assured we are looking into
some alternative ways to generate them :)
For those users looking for an update of the version including osgART
(http://www.osgart.org) - please be patient, we are working on the release of
osgART 2.x and would like to keep things in sync - there will be an update but
not right now.
Please give the installer a spin - let us know of your problems in the issue
tracker.
Now, head over to http://code.google.com/p/osgswig/
Cheers,
___

Re: [osg-users] How to define my own geometry in osgswig?
Hi Gerwin, it would be nice if this feature would work since if I have legacy c++ code that draws an asteroid, for instance, I would like to be able to just wrap that c++ code up in python and use it in osgswig.

Linh, Currently in osgswig you cannot directly override osg.Drawables in the target scripting language. This is partly because we have not enabled SWIG directors for this class, which are responsible for such cross-language inheritance. Also, Drawables are pure virtual/abstract which doesn't play nice with our directors. As an alternative, you might want to try and enable Directors for Geometry in osg.i: %feature(director) osg::Geometry; I'll consider this a feature request, will try this and see what the consequences on performance are. See the pyramid.py example for defining your own geometry without subclassing.

Re: [osg-users] osgswig binary release?
Hi Gerwin,
osgviewer cow.osg works for me. I did have OSG_FILE_PATH
set and I also tried to used absolute path to the cow.osg but it
for some reason it just couldn't find the mingw_osgdb_osg.dll and
mingw_osgdb_rgb.dll files I think.
The osgviewer could find those files ok (I could see it in gdb osgviewer). I
copy those osgdb_osg.dll and
osgdb_rgb.dll (and all the osgPlugins dll) to many places and and tried setting
OSG_LIBRARY_PATH etc but
still osgswig couldn't find the plugin.
Thanks Gerwin,
Linh

Linh,
Make sure your OSG_FILE_PATH environment variable is set correctly to a
location where cow.osg can be found (e.g. a directory where you extracted the
OpenSceneGraph-Data file). You must be able to run the regular osgviewer with
this file as well (osgviewer cow.osg).

Hi Gerwin,
I finally got the osgswig svn compiled with osg 2.4 using MinGW but I can't
seem to import the resulting DLLs (eg _osg.pyd) with python 2.5 win32 binary:
import sys;
sys.path.append('c:\\cygwin-1.7\\usr\\local\\src\\buildosgswig\\lib\\python')
import osg
Traceback (most recent call last):

File /usr/local/src/buildosgswig/lib/python/osg.py, line 7, in module
import _osg
ImportError: DLL load failed: The specified module could not be found.
But the _osg.pyd is in the python sys.path:

Dear Linh,
I'm not sure the osgswig svn still builds on and is tested on osg 2.3.4 (even
when using more mainstream linux compilers or MS visual studio). I personally
am still stuck on osg 2.4 (linux), other report that osg 2.6 and up works ok
with some known limtiations. We as osgswig contributors have not yet put clear
mechanisms in place to keep up with the various osg versions. Please post the
versions, error messages and other details of your findings on the osgswig
