OCIO TSC Meeting Notes

  • ACES 2 Dev Release
    • https://community.acescentral.com/t/aces-v2-developer-release/5427
    • Kevin - from the OT WG perspective, that means its 99.9% done from OCIO's perspective
    • Might be some parameter changes, one or two bugs but should be relatively solid
    • Down to just one edge case - uniformly sampling the LUT, which can be less than ideal in edge cases for pointy cusps. Not sure whether this change will end up in 2.0
    • Carol - "included" LMTs? That people might want in OCIO specifically?
    • Kevin - likely not, other than the "1.0 emulation"
    • Kevin - used the development version of the OT CTL, there's a bug in the release right now. Assuming they'll make a release soon
  • ACES github structure changes - OCIO config generator changes
    • Thomas - should be OK - will just need to be updating the config repo discovery etc 
    • Kevin - implementors were relying on "releases" for their updates, but for things that change more often (i.e. adding an IDT) can happen without a full "release"
    • Carol, Thomas - not sure it makes life easier for implementers... will need to talk with ACES about how they expect this to work
  • OpenFX Color Implementation (https://github.com/AcademySoftwareFoundation/openfx/pull/103)
    • Doug - PR has been open for over a year, been on OpenFX's roadmap for a long time to add basic color management support
    • It's influenced by OCIO, but doesn't strictly require OCIO. Basically to have a fallback for if someone doesn't have OCIO
    • Overlaps with Color Interop Forum work for standards with the texturing use case, but it doesn't cover their entire use case. 
    • They've taken the built-in configs and are extracting the names of the colorspaces they want included by default.
    • We may want to provide them some guidance around naming, aliasing, etc.
    • OpenFX is not implementing the conversion themselves - more relying on names that plug-ins and applications will be expected to support.
    • We should read through, and try and provide support and guidance to OpenFX as they tackle this. 
  • Review issues with "To Close" label
  • No labels
