Hi Gazebo Community!

This week’s meeting was held on 2026-08-17T18:00:00Z and the following is a summary:

## PMC Business

- None

## New agenda items

- **Gazebo-M Naming Process** : The namestorming process for Gazebo-M continues on the [namestorming sheet (not public)](https://docs.google.com/spreadsheets/d/1dveyz4Oc3akVfmwRcgmYxy9KUuy7b5aRJx6kUgb9gq0/edit?usp=sharing). The PMC agreed to extend the name filtering phase by one week to allow more community members and team participants to contribute.

## Updates

### C++20 Migration & Rendering

- **C++20 Progress & Ogre 1.9 Dependencies** (tracking issue: [gz-cmake#580](https://github):
  - C++20 builds are currently blocked by Ogre 1.9 compilation issues. Upgrading to Ogre 1.12 is pending PR review after ROSCon; the team discussed temporarily disabling Ogre 1.9 on the main branch if needed to unblock C++20 migration progress.

### Asset Format Strategy (COLLADA vs. glTF)

- **Discussion on COLLADA Support** : Discussed long-term deprecation of COLLADA (DAE) format support in favor of modern standards like glTF/GLB, as major tools (such as Blender) have dropped COLLADA. The team will outline a transition strategy—including conversion tools and Fuel compatibility checks—before removing COLLADA in a future release. Discussion will continue on [Zulip](https://openrobotics.zulipchat.com/#narrow/channel/526040-Gazebo-General/topic/Dropping.20Collada.20support.20in.20Gazebo/with/617059328).

### Core Libraries & Geometry

- **Physics & Simulation** : Fixed graded buoyancy calculations for rotated collision shapes in `gz-sim` ([gz-sim#3880](https://github.com/gazebosim/gz-sim/pull/3880)). Note: this behavior change will be documented in the migration guide.
- **Geometry & Math Utilities** :
  - Added `Centroid()` calculation to simple shape classes in `gz-math` ([gz-math#791](https://github.com/gazebosim/gz-math/pull/791)).
  - New PR adding mesh `Centroid()` calculation and fixing `Volume()` calculations for meshes offset from the origin in `gz-common` ([gz-common#877](https://github.com/gazebosim/gz-common/pull/877)).

- **COLLADA Loader Improvements** : Merged Part 2/3 of COLLADA loader robustness fixes in `gz-common` ([gz-common#831](https://github.com/gazebosim/gz-common/pull/831)).

### Buildfarm & Release Infrastructure

- **Ubuntu 26.04 (Resolute) Packaging for Jetty**:
  - Packaging progress for Ubuntu 26.04 ([release-tools#1503](https://github.com/gazebo-tooling/release-tools/issues/1503)) has successfully reached `gz-physics`, `gz-transport`, and `gz-fuel-tools`. Investigation is ongoing for `gz-rendering` and `freeimage`.
  - GitHub CI integration for 26.04 is underway with several PRs in review, including [sdformat#1702](https://github.com/gazebosim/sdformat/pull/1702).

- **New Releases** : Released `gz-msgs` (10.4.0 / 11.2.0), `gz-transport` (13.6.0 / 14.3.0), and their associated vendor packages.
- **Homebrew Ecosystem** : Rebuilt Homebrew simulation packages following Abseil, PyBind11, and FFmpeg updates, and reported a Homebrew-Zenoh issue ([homebrew-zenoh#21](https://github.com/eclipse-zenoh/homebrew-zenoh/issues/21)) which was fixed.

As always, the meeting notes are available at [🏛 Gazebo PMC meeting weekly agenda - Google Docs](https://docs.google.com/document/d/1RpVMkwiKqXKnDjqtkviz4qp73oehivf4Z1x-fTITgZY/).

The next Gazebo PMC meeting will be on 2026-08-24T18:00:00Z
