Ok, but is it supported in the animation system so if I load an scene that has material there the transparency is animated it will get animated automatically?

Yes, the OSG support texture subloading so you can just update your imagery and call dirty on it, and the OSG will automatically subload your data. You can also take advatange of Pixel Buffer Objects where supported. There is also a Quicktime plugin for Windows and OSX, and a xine-lib plugin under Linux. _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
