Which commit/version of NanoVDB should I use?

[NBickford-NV]

Hi bobluoluo! The NanoVDB API probably changed slightly; I think the solution here is to fix the gNanoVDB sample. Give me about an hour or two, and a new version should be up! The previous checked version was about 10 months ago, so likely something went out of sync.

Okay! Looks like the changes needed are a bit larger than I expected - NanoVDB now uses pointer offsets rather than child indices, and added new average and standard deviation fields which gNanoVDB doesn't write yet, so it'll take a bit longer for me to update the sample. In the meantime, I think commit AcademySoftwareFoundation/openvdb@cc79c0a might work - looks like version 8.1 included most of the breaking changes!

Hi, Neil -- I'd like to bump this. I've tested the above branch and a few others without success. I tried a few older commits and get some CUDA asserts. Can you confirm which specific commit you used to get the Nano export working? Thanks!

[NBickford-NV]

Hi digbeta! Apologies for the delay - I managed to get a new version about half-working (compiling and running but not yet exporting the volume correctly), but then had to switch to some high-priority tasks.

Going historically, the last changes to gNanoVDB were in c2609c5, so that would probably correspond to AcademySoftwareFoundation/openvdb@d31daaf - maybe that would work? Thanks!

I hit this as well with inability to use nanovdb. AFAIK nanovdb got added to the openvdb repo recently. With these older commits of openvdb, where are the nanovdb include files?
