For algorithmic changes related to the photogrammetric pipeline, please refer to AliceVision changelog.

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.

• Advanced Plugin Architecture: Dedicated sub-process isolation for Python nodes with independent local environments
• Integrated Development Tools:
  • Built-in Python script editor
  • Node’s source code hot-reload for rapid node development iterations
• Enhanced GraphEditor:
  • Dynamic output attributes enabling new workflow usages
  • New InputNode type enabling interactive evaluation without explicit computation
  • Multiple edge disconnection methods and node colorization for better user experience
  • Node notifications to attribute changes
• Enhanced 2D Viewer:
  • Initial timeline integration with sequence playback controls
  • New Reflectance Transformation Imaging (RTI) Viewer: Interactive visualization of albedo and normal maps with real-time lighting control
  • New Home Page: featuring pipeline templates and quick access to recent projects.

• New Pipelines
  • Color Calibration: Automated color correction from color charts
  • Raw to EXR conversion: Professional image format processing
  • Object Reconstruction: Targeted reconstruction with automatic object segmentation
  • Turntable Object Reconstruction: Streamlined workflow for rotating object capture
  • 360° Object Reconstruction: Reconstruction of complete dual-sided scanning
  • LiDAR Processing: Native E57 file import with integrated mesh generation
  • Multi-View Photometric Stereo: Advanced surface detail reconstruction with multiple light sources for each viewpoint.
• Pipelines Improvements
  • Camera Tracking pipeline: improved stability and reliability
  • Introduced experimental fine-grained pipelines for increased modularity and workflow flexibility
• Core Enhancements
  • Python Bindings Integration: Enhanced AliceVision accessibility with native Python support for streamlined Machine Learning workflows

AI segmentation nodes that identify and isolate image objects using natural language prompts, enabling intuitive content-aware processing through foundation models.

We're excited to introduce new experimental Machine Learning plugins available on MeshroomHub. These plugins showcase the future of Meshroom workflows, though they currently require developer setup and cannot be installed through the user interface yet.

See AliceVision 2.3.0 Release Notes for more details about algorithmic changes.

Based on AliceVision 2.2.0.

Release Notes Summary:

• Visualisation: New visualization module of the features extraction. PR, New QtAliceVision
• Support for RAW image files.
• Texturing: Largely improve the Texturing quality.
• Texturing: Speed improvements.
• Texturing: Add support for UDIM.
• Meshing: Export the dense point cloud in Alembic.
• Meshing: New option to export the full raw dense point cloud (with all 3D points candidates before cut and filtering).
• Meshing: Adds an option to export color data per vertex and MeshFiltering correctly preserves colors.

Full Release Notes:

• Move to PySide2 / Qt 5.13
• SfMDataIO: Change root nodes (XForms instead of untyped objects) of Alembic SfMData for better interoperability with other 3D graphics applications (in particular Blender and Houdini).
• Improve performance of log display and node status update. PR PR
• Viewer3D: Add support for vertex-colored meshes. PR
• New pipeline input for meshroom_photogrammetry command line and minor fixes to the input arguments. PR PR
• New arguments to meshroom. PR
• HDR: New HDR module for the fusion of multiple LDR images.
• PrepareDenseScene: Add experimental option to correct Exposure Values (EV) of input images to uniformize dataset exposures.
• FeatureExtraction: Include CCTag in the release binaries both on Linux and Windows.
• ConvertSfMFormat: Enable to use simple regular expressions in the image white list of the ConvertSfMFormat. This enables to filter out cameras based on their filename.

Based on AliceVision 2.1.0.

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

Full Release Notes:

• Viewer3D: New Trackball camera manipulator for improved navigation in the scene
• Viewer3D: New library system to load multiple 3D objects of the same type simultaneously, simplifying results comparisons
• Viewer3D: Add media loading overlay with BusyIndicator
• Viewer3D: Points and cameras size are now configurable via dedicated sliders.
• CameraInit: Add option to lock specific cameras intrinsics (if you have high-quality internal calibration information)
• StructureFromMotion: Triangulate points if the input scene contains valid camera poses and intrinsics without landmarks
• PrepareDenseScene: New imagesFolders option to override input images. This enables to use images with light patterns projected for SfM and MVS parts and do the Texturing with another set of images.
• NodeLog: Cross-platform monospace display
• Remove CameraConnection and ExportUndistortedImages nodes
• Multi-machine parallelization of PrepareDenseScene
• Meshing: Add option estimateSpaceFromSfM and observation angles check to better estimate the bounding box of the reconstruction and avoid useless reconstruction of the environment
• Console: Filter non silenced, inoffensive warnings from QML + log Qt messages via Python logging
• Command line (meshroom_photogrammetry): Add --pipeline parameter to use a pre-configured pipeline graph
• Command line (meshroom_photogrammetry): Add possibility to provide pre-calibrated intrinsics.
• Command line (meshroom_compute): Provide meshroom_compute executable in packaged release.
• Image Gallery: Display Camera Intrinsics initialization status with detailed explanation, edit Sensor Database dialog, advanced menu to display view UIDs
• StructureFromMotion: Expose advanced estimator parameters
• FeatureMatching: Expose advanced estimator parameters
• DepthMap: New option exportIntermediateResults disabled by default, so less data storage by default than before.
• DepthMap: Use multiple GPUs by default if available and add nbGPUs param to limit it
• Meshing: Add option addLandmarksToTheDensePointCloud
• SfMTransform: New option to align on one specific camera
• Graph Editor: Consistent read-only mode when computing, that can be unlocked in advanced settings
• Graph Editor: Improved Node Menu: "duplicate"/"remove"/"delete data" with "From Here" accessible on the same entry via an additional button
• Graph Editor: Confirmation popup before deleting node data
• Graph Editor: Add "Clear Pending Status" action at Graph level
• Graph Editor: Solo media in 3D viewer with Ctrl + double click on node/attribute
• Param Editor: Fix several bugs related to attributes edition
• Scene Compatibility: Improves detection of deeper compatibility issues, by adding an additional recursive (taking List/GroupAttributes children into account) exact description matching test when de-serializing a Node.
