Meshroom 2025.1.0 (2025/08/18)

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.

Prebuilt binaries on this page are all-in-one packages including AliceVision and all required resources.
To start the application, unzip the archive and launch Meshroom executable.
A video overview of Meshroom is available here.

Requirement: NVIDIA CUDA-enabled GPU (compute capability >= 2.0).

Linux: on some distributions (e.g Ubuntu), you may have conflicts between native drivers and mesa drivers, resulting in an empty black window. In that case, you need to force usage of native drivers by adding them to the LD_LIBRARY_PATH: LD_LIBRARY_PATH=/usr/lib/nvidia-340 ./Meshroom
You may need to adjust the folder /usr/lib/nvidia-340 with the correct driver version.

Release Notes Summary

• 3D Viewer: Load and compare multiple assets with cache mechanism and improved navigation
• Display camera intrinsic information extracted from metadata analysis
• Easier access to a more complete sensor database with a more reliable camera model matching algorithm.
• Attribute Editor: Hide advanced/experimental parameters by default to improve readability and simplify access to the most useful, high-level settings. Advanced users can still enable them to have full access to internal thresholds.
• Graph Editor: Improved set of contextual tools with duplicate/remove/delete data actions with From Here option.
• Nodes: Homogenization of inputs / outputs parameters
• Meshing: Better, faster and configurable estimation of the space to reconstruct based on the sparse point cloud (new option estimateSpaceFromSfM). Favors high-density areas and helps removing badly defined ones.
• Draft Meshing (no CUDA required): the result of the sparse reconstruction can now be directly meshed to get a 3D model preview without computing the depth maps.
• MeshFiltering: Now keeps all reconstructed parts by default.
• StructureFromMotion: Add support for rig of cameras
• Support for reconstruction with projected light patterns and texturing with another set of images
