关于osgearth加载shp文件问题

lyz123

请问下大佬，为什么我加载shp文件的时候，有的shp文件可以在earth上显示，有的却不能显示，shp文件是没有问题的，下面是加载代码
       Style style;
        LineSymbol* ls=style.getOrCreateSymbol<LineSymbol>();
        ls->stroke()->color()=Color::Yellow;
        ls->stroke()->width()=10.0f;
        style.getOrCreate<osgEarth::AltitudeSymbol>()->clamping() = AltitudeSymbol::CLAMP_RELATIVE_TO_TERRAIN;  
        style.getOrCreate<osgEarth::AltitudeSymbol>()->technique() =osgEarth::AltitudeSymbol::TECHNIQUE_DRAPE;
        style.getOrCreate<osgEarth::AltitudeSymbol>()->binding() = osgEarth::AltitudeSymbol::BINDING_VERTEX;

        osgEarthrivers::OGRFeatureOptions featureOptions;
        featureOptions.url()="F:\\Progams\\bou2_4l.shp";
        osgEarth::Drivers::FeatureGeomModelOptions geomOptions;
        geomOptions.featureOptions()=featureOptions;
        geomOptions.styles()=new StyleSheet();
        geomOptions.styles()->addStyle(style);
        geomOptions.enableLighting()=true;

        ModelLayerOptions layerboundryOptions("china_boundry",geomOptions);
        m_pMap->addModelLayer(new ModelLayer(layerboundryOptions));

请问你最后一句的addmodelLayer不会报错吗？我这里显示它是一个私有成员函数，用不了
