[osg-users] Python users

[Rizzen]

Hi,

What is the best OSG python library/wrapper to use? I see there are
various versions: pyOSG, PyOSG and osgPython. Some project showed no
activity since 2003. Some projects showed activity in the news yet files
are a lot older. PyOSG does not seem to have a SVN on SourceForge, just
old tarballs.

I am planning to use Boost:python in my project too.

Thanx,
Rizzen

I have used swig generated Python bindings from osgSwig 
http://code.google.com/p/osgswig/


I have used it with 2.9.5, not knowing weather recent SVN big changes 
have broken the build

If you're planning on using boost.python you might be interested in 
trying the wrapper project I've started, which wraps some of OSG but not 
all using boost.python. It's located here:


http://code.google.com/p/osgboostpython/

I started it just for fun, and wrapped most of the basics to make a 
working OSG application (matrices, vectors, geometry, textures, some 
event handlers and callbacks, viewer, etc.). Martin Mueller also 
contributed some wrappers at one point. It's still not close to being 
complete, but might be sufficient for your needs, and you could help 
improve it too.


Let me know if you want more info or if you decide to use it and you 
need help getting started.

Hi,

Thanks to make the osgboostpython code!
 
i'm running osgboostpython on mac osx 10.6 (osg svn, 64-bit)
boost+python support from source (1.41)

now i'm tring to runs some examles, 
but i have problems using the code from the main page :

In [12]: s.setTextureAttributeAndModes(0, t, osg.StateAttribute.Values.ON)

Traceback (most recent call last):
  File "", line 1, in 
AttributeError: type object 'Values' has no attribute 'ON'


any clue on what's wrong?


p.s.

... tring to build osgboostpython , seems that it don't recognize the .dylb 
files
so i had to simlink *.dylb to *.so.

Hi Massimo,

Sorry, my first reply went to you directly... I don't know why, 
sometimes "reply" replies straight to the sender, even though the 
mailing list should be changing the headers so that replies go back to 
the mailing list...


i'm running osgboostpython  on 
mac osx 10.6 (osg svn, 64-bit)

boost+python support from source (1.41)


Please note that I've never tried to build it on Mac OS X, so your input 
will be valuable (as below).

Yes, the enums were changed to const members to fit better with the C++ 
style but I didn't change the code on the front page  :-(


Try to use osg.StateAttribute.ON instead (without the .Values)...

See 
http://code.google.com/p/osgboostpython/source/browse/trunk/osgBoostPython/lib/osg/__init__.py


I've updated the front page now. Sorry about that.

You could possibly change the jam files so that it uses .dylib files 
instead, but I have no clue how to do that. Perhaps the bjam / jam / 
boost.build documentation can help you.


Thanks,

Hi Jean-Sébastien,

thanks!
running the latest notes from the wiki main page all works fine.
now i'm exploring the example code.

a question :

have you never tried to add a python osgviewer inside a PyQt4 (or wx-python) 
gui ?

thanks,

Massimo.

Hello Massimo,

Good to know you're getting better success now.


have you never tried to add a python osgviewer inside a PyQt4 (or wx-python) 
gui ?


No, sorry. If you try it let me know, I would be very interested to know 
if it works well. Also if you could contribute a small example of that 
in action I would gladly add it to the osgBoostPython examples.
