How to visualize the voxel grids or .vdb file generated by openVDB? When I #include <openvdb/viewer/Viewer.h>, it shows no such file or directory

Hello @JeffreyYH - the Viewer files are not installed as part of the OpenVDB installation (this is a bit weird I know), so I'm not really sure if they were ever meant to be fully downstreamed as a finished public API. The files in openvdb/viewer are only used to build the vdb_view (openvdb_view.cc) binary. You can use this binary or various DCCs (such as Houdini) to visualize a VDB. Should you wish to build your own application that visualizes VDBs, you'll have to copy the entire viewer directory and incorporate it into your project.

We could add an option to build this support into libopenvdb.so or build a separate libopenvdb_view.so which incorporates this functionality. Would require more discussion.
