I would like to inquire whether the information about '.ingp' files is publicly available.

[julia6945]

I would like to inquire about the possibility of developing a simple viewer for '.ingp' files.
I am considering creating a loader for '.ingp' files.
Is there any publicly available information on the structure of '.ingp' files that could help in developing a viewer?
Alternatively, is the part of the 'instant-ngp' open-source code that loads '.ingp' files publicly available?

If anyone has information on this, I would greatly appreciate it.
