Detailed Description

This class defines the meta data stored for each grid in a segment.

A segment consists of a FileHeader followed by a list of FileGridMetaData each followed by grid names and then finally the grids themselves.

Note

This class should not be confused with nanovdb::GridMetaData defined in NanoVDB.h Also, FileMetaData is defined in NanoVDB.h.
