HI Terry, If you want to automatically modify a scene graph at load then the best thing to do is write a osgDB::Registry::ReadCallback to override the normal load calls. Have a look at the callback interface in include/osgDB/Registry and what to do should become clear.
Bascially it'll be your resposibility to do the load, so just call the registry readImplementation to load the model then traverse the resulting model changing what you want to change, then return the final modified model. Robert. On 11/9/06, Terry Welsh <[EMAIL PROTECTED]> wrote:
When loading model files, it would be nice if OSG could detect if a node contains any type of transparency (in vertex colors or textures). If so, it could turn on GL_BLEND and put the geometry in the correct bin. Is there functionality like this anywhere already? Perhaps in some specific loaders? It does not appear to happen when I load a .osg file. -- Terry Welsh - mogumbo 'at' gmail.com www.reallyslick.com | www.mogumbo.com _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
