Meshroom 2025.1.0 (2025/08/18)

[fabiencastan]

Meshroom has now become a node-based visual programming toolbox for creating, managing, and executing complex data processing pipelines, with a new plugin architecture.
Standard computer vision pipelines such as photogrammetry, camera tracking, HDR panorama, Lidar Meshing, Raw image files conversion and color calibration are now unified within the AliceVision plugin, featuring numerous improvements and optimizations.
Additionally, new AI-powered capabilities include a semantic segmentation plugin and a collection of open-source extensions available via the new MeshroomHub: https://github.com/meshroomHub. This platform enables Gaussian Splatting, monocular depth estimation, and other exploratory features, welcoming developer contributions to expand and enhance these capabilities for upcoming releases.

This discussion was created from the release Meshroom 2025.1.0 (2025/08/18).

[MrClock8163]

I really appreciate all the work done here.
I downloaded the precompiled package, and I plan to check out this release tomorrow, but I must ask:
I thought the whole point of the new plugin architecture is to avoid having to ship huge datasets and models with the base build, and give users the opportunity to only add what they really need. Yet this release is 10+ GBs out of the box? How's this supposed to work then?

[natowi]

The image segmentation is an important part of the pipelines and therefore bundled with the release. Otherwise people would not be able to use it, as the dev-setup is not for everyone.
I think with an upcoming release those parts could be moved to Meshroom Hub, once there is an easy way to install plugins from the UI.
