A question about OSGDB::readNodeFile

[kuazhangxiaoai]

OSG is a great work.
I have a group of OSGB files with LOD format. I just want to get all vertex information from those files by OSGDB::readNodeFile. It is unnecessary to read all OSGB files, but just read root file of each subdirectoy, right?

Thanks for your answers.

The vertex arrays are all stored in osg::Geometry within the files so if you want to analyze all that data you'll need to load all the tiles.
