The vsgPoints library supports point cloud quantization and database paging using vsg::PagedLOD so that would be the best place to start:

https://github.com/vsg-dev/vsgPoints

The README.md gives some instructions on the vsgpoints_example program that is able to load, process into LOD/PagedLOD and render large point datasets.

There is a ASCII ReaderWriter that handles loading .3dc and . asc point cloud formats and BIN ReaderWriter that can handle some specific binary data.

These won't directly help you with reading PLY format but might help give you inspiration. PLY format is simple enough that just writing your own loader might be the best approach.
