clipPlane状态集删除

wang15061955806

osg::ClipPlane cp1 = new osg::ClipPlane();
osg::ClipPlane cp2 = new osg::ClipPlane();
cp1->setclipplaneNum(0);
cp1->setclipplaneNum(1);
root->getOrCreateStateSet()->setAttributeModes(cp1);
root->getOrCreateStateSet()->setAttributeModes(cp2);
给节点添加两个clipplane状态后，怎样将这两个状态删除，直接用RemoveAttribute(osg::Stateset::CLIPPLANE)好像只能删除一个状态，我要把所有的clipplane状态都删除，怎么弄？

我现在直接使用的是:
osgObj->        getOrCreateStateSet()->setMode(GL_CLIP_PLANE0,osg::StateAttribute::OFF);
osgObj->        getOrCreateStateSet()->setMode(GL_CLIP_PLANE1,osg::StateAttribute::OFF);
osgObj->        getOrCreateStateSet()->setMode(GL_CLIP_PLANE2,osg::StateAttribute::OFF);
osgObj->        getOrCreateStateSet()->setMode(GL_CLIP_PLANE3,osg::StateAttribute::OFF);
osgObj->        getOrCreateStateSet()->setMode(GL_CLIP_PLANE4,osg::StateAttribute::OFF);
osgObj->        getOrCreateStateSet()->setMode(GL_CLIP_PLANE5,osg::StateAttribute::OFF);
每次都设置6个附加裁剪的状态为关闭，可以将节点的裁剪面删除，大家有更好的方法吗？
