I know setting an empty program is the way this used to be done. And it seemed to work for some time. But in my case it doens't.
In the apply method of osg::Program, a call to glUseProgram(0) is issued when the program object is empty. According to http://stackoverflow.com/questions/13546461/what-does-gluseprogram0-do this is not a reliable way of falling back to FFP, and it seems to depend heavily on opengl profile and probably also on the driver... Are there any alternative solutions? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=58183#58183 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
