OCIO TSC Meeting Notes

• OpenImageIO / OCIO interaction:
  • Circular dependency between the two projects.
  • Current workflow is build OCIO without apps, build OIIO with apps, build OCIO apps.
  • Proposal to replace OIIO dependency with OpenEXR. This would have slightly less functionality for OCIO tools, but in practice many people will use oiiotool for this purpose.
  • Doug - Are these tools used in production?
  • ocioconvert can use the GPU - which oiiotool does not.
  • ociolutimage might be used.
  • WIth OpenEXR the library could be built "earlier" if you were building all of the VFX reference platform.
  • Remi has been volunteered to look at this (with help from Michael)
  • No visual aide to see which apps are affected, but they should only be those under the following conditional https://github.com/AcademySoftwareFoundation/OpenColorIO/blob/415c5837097cc602682ce55c111a24bb91b5be60/src/apps/CMakeLists.txt
• OpenColorIOConfigs:
  • Upcoming release of CG ACES config, Lots of projects use Twitter to announce releases, do we want to do the same?
  • Kevin - It's very little effort to announce we have made a release - It is possibly infinite effort to respond to all the users questions
  • Thomas - It's not a lot of effort on the projects he has been involved with
  • Carol has volunteered to be involved
  • ASWF has some resources that we might be able to lean on
  • Patrick - We could link them to the slack channel as the place to get more info
• Application support list
  • On the old website we had a simple list of apps that supported OCIO.
  • Should we update this to a list that shows v1 / v2 / GPU support?
  • How granular should the matrix be? Should it include features like the gamut compressor?
  • Who is the audience of this information? Is it more of a marketing splash page, or is it a technical reference?
  • Liam has made a table already: https://liamcollod.notion.site/OCIO-Supported-Softwares-35474fd5cf394fd796449807fe8b5ab6
  • This information was manually scraped, through reading release notes or searching documentation, starting from the old list
  • Linux Foundation might be able to help with a compliance / conformance program that could remove some of the human curation process behind checking all of these tools.
  • UI / UX guideline group might also have input on how to judge the completeness of a DCC's implementation.
  • Perhaps it should go on the wiki, to lower the barrier of entry for people to add their applications.
  • New ACES OCIO config release might raise lots of questions about which version of OCIO is required (and which is provided by their DCC).
• Documentation
  • Does the documentation website have a separate branch that it pulls from? There are mistakes and layout bugs at present.
  • You can just push to the master branch (or merge) and it will update fairly quickly. There may be quirks regarding python (needing a code freeze) but these are manageable by our devs.
• Pull requests and issues
  • please help!
• Doug has raised an issue regarding "Default configs"
  • Will likely be discussed at the next TSC meeting.
