Hi Gazebo Community!

This week’s meeting was held on 2026-07-13T18:00:00Z and the following is a summary:

PMC Business

  • None

New agenda items

  • ROSCon 2026 PMC Meeting & Hackathon Planning:
    • Community ideas and proposals are actively being collected for the upcoming ROSCon 2026 PMC meeting (Monday) and Hackathon (Friday).
    • Please contribute ideas, topics, and motivations using the shared documents: ROSCon 2026 PMC Meeting Ideas (not public) and ROSCon 2026 Hackathon ideas (Public).
    • The hackathon is designated as a public event open to anyone interested in contributing in order to encourage new community participation in open source.
    • Options for sponsoring hackathon lunches are currently being investigated, and plans for after-event social dinners (such as a Gazebo contributors dinner) are being considered.
  • Project Leadership Nominations: A reminder was shared that the self-nomination window for project leadership roles remains open, but will close soon.

Updates

Infrastructure & Buildfarm

  • Buildfarm Priorities & Issues: All existing buildfarm priority issues have been resolved, except for one new warning regarding CMake 4.4 handling of backslashes: CMake Warning: Policy CMP0219 is not set in GzStringAppend.cmake. A pull request was opened to apply a policy-based interim fix, while leaving the issue open to track a future permanent resolution.
  • Buildfarmer Dashboard: The temp buildfarmer dashboard is nearly complete and ready for review/testing across projects. Suggestions and feedback are welcome on pull request #263 or in the upcoming Zulip thread.

Package & Performance Updates

  • gz-sim & gz-rendering GUI Performance: Removed redundant calls that pre-rendered visual children twice per frame, which are now superseded by a base class call. This optimization resulted in significant startup speed improvements when loading large scenes (tested with 3,000 shapes). These changes have been merged across multiple target branches: Rotary #1309, Jetty #1311, Ionic #1312, and Harmonic #1313. Additional optimizations such as pausing rendering when the scene is unchanged were evaluated but determined to be too risky due to reliable trigger rules.

As always, the meeting notes are available at :classical_building: Gazebo PMC meeting weekly agenda - Google Docs.

The next Gazebo PMC meeting will be on 2026-07-20T18:00:00Z
