osg 动态读取PageLOD数据文件后处理数据节点 callback 方法

创建读取文件回调类

//.h

class CReadFileCallbackEx : public osgDB::ReadFileCallback
{
public:
   CReadFileCallbackEx();
   virtual ~CReadFileCallbackEx();
   virtual osgDB::ReaderWriter::ReadResult readNode(const std::string& filename, const osgDB::ReaderWriter::Options* options);
};

//.cpp

osgDB::ReaderWriter::ReadResult CReadFileCallbackEx::readNode( const std::string& filename, const osgDB::ReaderWriter::Options* options )
{
   osgDB::ReaderWriter::ReadResult rs = osgDB::ReadFileCallback::readNode(filename,options);
   if (rs.validNode())
   {
       //处理数据节点,可以设置显示颜色等参数
       osg::Node* pNode = rs.getNode();
}
   return rs;
}
