osg::ref_ptr<osg::Program> createProgram()
{
    osg::Program *program = new osg::Program();
    program->addShader(new osg::Shader(osg::Shader::VERTEX,vertSource));
    program->addShader(new osg::Shader(osg::Shader::GEOMETRY,geomSource));
    program->addShader(new osg::Shader(osg::Shader::FRAGMENT,fragSource));
    program->setParameter(GL_GEOMETRY_VERTICES_OUT_EXT, 3);
    program->setParameter(GL_GEOMETRY_INPUT_TYPE_EXT, GL_TRIANGLES);
    program->setParameter(GL_GEOMETRY_OUTPUT_TYPE_EXT,  GL_TRIANGLES  );
    return program;
}
