Thank you very much... it worked!!
either
%inline %{
osg::Geode *NodeToGeode2(osg::Node *b) {
return dynamic_cast<osg::Geode*>(b);
}
%}
or
%extend osg::Node {
virtual osg::Geode* asGeode() {return dynamic_cast<osg::Geode*>(self);}
};
The Cmake projects worked fine (just some mods to standard FindOSG), I
spent some time to find out how to install correctly into site_packages
If I' m correct, the dll must be renamed .pyd and the generated py must
be copied inside the site_packages
I noticed the compile time of the _osg project is quite slow (at least
on my machine) do you think it would be possible to split the big osg
wrapper into smaller pieces to
both speed up build time and separate original (yours) and added (mine)
Do you plan to insert your CMake files into the osgswig svn?
Having things in svn will really help a lot the development
I' m planning to experiment further and then try to add site_packages
installation to cmake if do not find a better way to work
thanks again
