求助：HUD无法显示高度大于0的模型？

HUD实现：

1. osg::ref_ptr<osg::Node> EditIntersectionCommand::getHUDCamera(const osg::ref_ptr<osg::Node>& aNode)
   
2. {
   
3.     osg::BoundingSphere sphere = aNode->getBound();
   
4.     osg::Vec3d sphereCenter = sphere.center();
   
5.     double radius = sphere.radius();
   
6.     osg::Camera* camera = new osg::Camera;
   
7.     double left = sphereCenter.x() - radius;
   
8.     double right = sphereCenter.x() + radius;
   
9.     double bottom = sphereCenter.y() - radius;
   
10.     double top = sphereCenter.y() + radius;
    
11.     //设置透视矩阵
    
12.     camera->setProjectionMatrixAsOrtho2D(left, right, bottom, top);
    
13.     camera->setReferenceFrame(osg::Transform::ABSOLUTE_RF);
    
14. 
    
15.     //得到默认设置
    
16.     camera->setViewMatrix(osg::Matrix::identity());
    
17.     //设置背景为透明，否则的话可以设置ClearColor
    
18.     camera->setClearMask(GL_DEPTH_BUFFER_BIT);
    
19.     //设置渲染顺序，必须在最后渲染
    
20.     camera->setRenderOrder(osg::Camera::POST_RENDER);
    
21.     camera->addChild(aNode);
    
22.     camera->getStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::OFF);
    
23.     return camera;
    
24. }

但如果Node内的Geometry Z值设为大于零的数，显示不出来，<=0都可以显示出来！跪求解答啊！！！！

急求急求！！！盼高手帮忙！！！

camera->setViewMatrix(osg::Matrix::identity());

就是这样设置的，不行啊

array

setProjectionMatrixAsOrtho2D事实上相当于限制远近平面在[-1, 1]区间内，我想您绘制的内容超出了这个范畴
