- Confirm quorum
Quorum is present.
- Secretary
Secretary is Andre Pradhana.
- Migration from PyBind11 to NanoBind
Matthew Cong presented a solution to handle NanoBind dependency by using pip. He has done work on the NanoBind-side to allow this workflow. The solution with Git-subtree/submodule is brittle because it can run into firewall issues.
It was re-iterated that NanoBind is preferred because of zero-interop on the GPU side.
Dhruv Govil pointed out that PyBind is used by other projects for its support for multiple inheritance (which NanoBind doesn’t support).
- Greg's ASWF membership
Greg will follow up with John Mertic to be added to ASWF organization.
- FVDB
NVIDIA team presented a presentation on fVDB, a project that is for consideration to be adopted by OpenVDB project. It is a framework to do spatial reasoning on 3D volumetric dataset, which includes deep- learning.
The main dependencies is pytorch. The project will live in its own
directory, parallel to the openvdb directory.
Ken will bring up the need for GPU-support in the CI in the TAC meeting. TSC members will be added to the private fVDB repository for further investigation. Jonathan Schwartz provided us with documentation.
- Next meeting
Next meeting is on May 7th, 2024. 2pm-3pm EDT (GMT-4)
