Re: [osg-users] Open Asset Import Library
I've just tried to load Collada object with materials with the help of your assimp plugin, and it worked fine. However, blend files created with Blender 2.64 didn't produce any visual output. So it turns out assimp isn't the holy grail :| ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Open Asset Import Library
Hi Michael, AssImp use a simpler scene graph to manage read data, in which one node could have a transformation matrix and multiple meshes, and multiple child nodes. Materials (including textures) are managed globally in a map so objects could share one texture. But one mesh can only be linked to one material. I personally think Assimp will divide any object into meshes to support multiple materials if required, but I don't know Blender output would be handled in similar way in such case.

Wang Rui, I research what format best to use for moving objects from Blender to OSG, and I see Assimp claiming to load Blender files directly. Since you said you wrote the plug-in already for it, I'd like to try it out. I have a follow up question: can I possibly differentiate Blender model from Blender material to have several skins for the same material in OSG? Does your plug-in do anything of the sort? Thanks. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Open Asset Import Library
And 2 positive cents for Open Asset Import Library, we've successfully used it in the past to import various 3D models (.3ds, .obj, etc.). As far as I know, it does not support model exports.

Re: [osg-users] Open Asset Import Library
Hi Chris, Oh, I'm just working on a new integration project of OSG and different kinds of 3rdparty libraries. Ande I've already wrote plugins of FreeImage and AssImp, as I think both are great for importing and exporting, too. https://github.com/xarray/osgRecipes/tree/master/integrations Unfortunately I haven't had time to test my AssImp plugin yet (the FreeImage one works well now and I'll try to submit it soon), so if you think it valuable and possible for use, please don't hesitate to test it and help me improve it. :-) Cheers, Wang Rui 2012/6/7 Chris Hanson > http://assimp.sourceforge.net/main_features.html > > > Anybody used this? > > Might be interesting to begin an optional plugin to load files via this > library, if you have it.
