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:

  • https://docs.google.com/spreadsheets/d/1Yq3PkDIcbcpYYAKTJcqyegROyydf4kD5NsQlGTg2yZc/edit#gid=0

  • Getting implemented next week, open for last comments before then, and then we'll see how it works for us and update from there

• 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.
