Re: [osg-users] java osgSwig = binding / wrapping not available easyly ?
Hi Nicolas, keep us updated on your osg4j project, sounds nice. Osgswig can use some of doxygen's code parsing XML metadata by converting it into code comments. In terms of parsing headers automatically, I think GCC-XML does a good job (see the cableSWIG project).

Re: [osg-users] java osgSwig = binding / wrapping not available easyly ?
Hi Soaring, you're right about osgSwig being targeted at Python mainly. We as osgswig maintainers have already had some requests on how to make things work in Java but no one has stepped up yet to do the integration yet. I know of two new attempts to do the Java bindings, one of which likes to remain under the radar, and the other was mentioned by Rafa Gaitan on the list: We have a collegue (Leo Muñoz) working on a solution using osgIntrospection. The project is called osgGenerator and the idea is create a (nodekit) to generate wrappers for other languages using osgIntrospection. It's his final degree project so I hope he finish it in a few months. He is working of course in the nodekit and in a java generator. The project it's in his infancy but could be a usefull nodekit. the svn url is: svn co http://corsario.codemaniacs.com/osggenerator/trunk I've been in touch with Rafa on this, and maybe this might be integrated in osgswig one day. In the not too distant future I plan to do a code-sprint to make osgswig more robust and compatible with the newer osg versions. keep us updated on your findings, Gerwin On Sat, Apr 25, 2009 at 11:55 PM, Soaring nicolas.george...@gmail.com wrote: hi everyone, i recently move my scenegraph beginner's work from ogre engine to openscenegraph wich i feel is more powerful. i read the quick start guide (about 100 page, very quick lol ) to learn basic concepts of osg i would like to use java langugae and swing (for MIH), so osgintrospection is a first point of start as osgSwig... but : osgSwig seems to be maintain only for python, wich is a good language i guess, but not usefull for me. so i downloaded osgSwig source on my ubuntu and try to compile for my personnal java use but documentation and samples are not up to date (and not existing for java as i see). furthermore, i read on forum's post that dynamic language' are great supported but bytecode language (like java c#) are not supported very well (it seems some hacks are needed for memory management cause osg use internal pointer memory management as a local garbage collector (to sum up) wich can be a problem with jni). another project, javaOsg, seems to be down, and as i understand, manual binding must be made so project can't follow osg update as far as needed by the communauty... so forget it ! my goal is not to develop my software in c++ (too much time to spend with memory and string management for me, except with boost etc.. but it's not my cup of thea as we say in french !), not learn another langugage (like python), and use java for the great support on multiplatform and Rich Client Platform available with netbeans or eclipse. so i read lot of post, lot of documentation before posting my request, in fact, to sum up, is there an automatic way to bind java with osg automatically in a easier way to follow osg update in a minimal time lost ? if someone as successfully compile a java version of osgSwig for linux 64 (ie ubuntu) it will be very nice to update that work on the osgSwig project for the communauty..and me too ;-) i hope that someone could help me in a technical way (and not just redirect on osgSwig... from i come !) thanks by advance ! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=10866#10866 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
