[osg-users] ANN: osgPython (SWIG) 2.2.0

[René Molenaar]

Nice to hear!

I just merged the files and commited the new trunk.
Readme:
---------------------------------------------------------------------
Swig wrappers for OpenSceneGraph.

This is the new trunk of osgswig.

 http://osgswig.googlecode.com/svn/trunk
 or for members: https://osgswig.googlecode.com/svn/trunk

it is a merge of the original osgswig branch and
the branch used for the VRmeer Project (python and perl).

The merge contains new cmake files, that build the
following modules;

osg
osgDB
osgFX
osgGA
osgUtil
osgViewer

There is one (new) simple test example:
examples/python/simple/simpleosg

The default cmakesetting make these modules for python.

It is most recently tested with
swig 1.3.33
OpenSceneGraph 2.3.4

The merge also still contain all the files and documentation from the
original osgswig.
Revision 95 of:
 http://osgswig.googlecode.com/svn/
 or https://osgswig.googlecode.com/svn/ (for members)
contains the original osgswig.
---------------------------------------------------------------------

I think the files in the root svn folder can be deleted now,
just leaving the trunk folder.

For installing the python modules a python setup.py can be made
(look for a setup.py template).

cmake can then invoke "python setup.py install" to place the files in the
site-packages dir.
This file can then also be used for creating binary distributions ("python
setup.py bdist_wininst")

I did not look into the splitting the osg.i file,
maybe there is some swig function for this.

Maybe cmakefiles are needed for the other languages/modules.
If you have important fixes please tell.

Good luck,

René
