OCIO TSC Meeting Notes

  • Adding Cuneyt Ozdas to the committers list
    • Cedric Fuoco has been contributing to OCIO from Autodesk, but has moved to the OpenRV project
    • Cuneyt Ozdas joining OCIO dev from Autodesk! Was lead dev on OCIO integration in 3DSMax!
    • Doug creating a PR to request to add him to the committers list
    • Next TSC meeting will spend time on Leadership votes, TSC member commitments, and new committer final approval
  • ACES 2.0 timing / roadmap
    • ACES 2.0 is imminent. Got an email from Alex Forsythe asking for our drop dead date we'd need ACES 2.0 release in order to support in OCIO 2.4
    • Remi might be up for helping implement, will be dependent on timing 
    • Kevin - thinks a couple of months to implement is reasonable. Leadership of OT group will likely be available to help. There will be a CTL translation - which may or may not help. Man dev was done in Blink, which might be slightly more useful for GPU implementation. 
    • Could start looking at current code for an idea 
    • Will create an issue on the OCIO repo and start aggregating info and investigating
    • One particular algorithm is subject to change - the gamut mapping
    • Most challenging to implement will be the gamut mapping - might not be analytically invertible 
    • Will stay in closer contact with Kevin / ACES leadership as release gets closer
  • GitHub Label Revision:
  • PRs to review #1933 (More Linux wheels)
    • Doug logged an issue due to a crash - didn't think it would be an issue, but it seems like it is 
    • Remi has a PR using the new ABI, we'd like to get this out quickly as it's crashing on applications using 2024 VFX reference platform
    • Michael will take a look at the PR 
    • Kevin also has a very draft PR on updates to ocio archiving - definitely needs eyes as it changes API/ABI
    • Mark has a PR for AVX512 - would be good to test it on Windows https://github.com/AcademySoftwareFoundation/OpenColorIO/pull/1932
    • Should check in the paid runners section
  • OpenSSF Badge Review (https://www.bestpractices.dev/en/projects/2612?criteria_level=1)
    • Overview of all ASWF projects: https://docs.google.com/spreadsheets/d/1bEacUNFizeT8QtfsvqiRNNgvty8_tweHjassHko6OhQ/edit#gid=67150143
    • MaterialX & OpenEXR are the furthest along, in case anyone is curious
    • TAC is working through requirements to Gold/Silver badges, to see what requirements are truly not relevant / not achievable for ASWF projects, so we can get more projects over the threshold (it's technically required for a project to achieve silver/gold to be adopted, though none of our projects have.)
    • Carol has taken a first stab at reviewing our Silver requirements, we are further along than we might think. Biggest areas of issue are in Quality & Security, and some may be easy (ish) fixes/adds.
    • The project MUST automatically enforce its selected coding style(s) if there is at least one FLOSS tool that can do so in the selected language(s).
      • We should probably do this - but which one? Throw a bunch of clang styles at it and see which one has the least diff? And then just pick a python style (pep8? black?)
      • Autodesk tried to follow existing style as much as possible when re-writing major parts for ociov2
      • Carol will create an issues to propose this work, and then we'll need the CI checks to verify it
      • could look into git pre-commit hooks
    • If you have time, would appreciate more eyes on this / opinions before next week's TAC meeting.
