转眼十几天过去了，还没更新，还是太心急了，不要急，一不跳槽，二没开除，完成当天任务即可。快就是慢，慢就是快。
继续看
osg::Object* readObjectFile(const std::string& filename,const ReaderWriter::Options* options);
代码是：
inline osg::Object * readObjectFile_lf(const std::string& fileName)
{
return readObjectFile(fileName, Registry::instance()->getOptions());
}
分别用到了
osg::Object* readObjectFile(const std::string& filename,const ReaderWriter::Options* options);
osgDB::Registry* osgDB::Registry::instance(bool erase);
ReaderWriter::Options* osgDB::getOptions();
好，就到这里，短小精悍。
