2024-04-23 Compositor meeting notes


  • Habib Gahbiche
  • Omar Emara

Notable changes:

  • Improve interactivity for GPU compositing PR #120656

  • Updates from Habib:

    • Render/domain size visualisation patch
    • Fast viewing with shortcuts
      • Need general agreement between users
      • Make proposal from our side
      • Sergey will catch up with feedback, and help with finishing design from our side
    • Exposing interpolation methods
      • Mark as good first issue
  • Updates from Omar:

    • Fast gaussian
      • Numerical stability
      • Split into smaller order filters. Omar has implementation, but needs debugging
  • Ready to move GPU compositor out of experimental

    • Check on split vs. unified setting (for viewport vs. final compositors) with Brecht
    • Check behavior of GPU compositor scene on a server machine without GPU
  • Omar will check on software rasterization performance

  • Gabor patch

    • Omar might pick it up if needed for 4.2

Practical Info

This is a fortnightly video chat meeting for planning and discussion of VFX & Video in Blender. Any contributor (developer, UI/UX designer, writer, …) working on these areas in Blender is welcome to join and add proposed items to the agenda.

For users and other interested parties, we ask to read the meeting notes instead so that the meeting can remain focused.


Gotta say, it’s awesome to say the composition/domain patch and the fast viewing being taken into consideration so soon. Thank you for your work!

PS: (I was involved in the discussion about the fast viewing, if I can be of any help let me know)
