Release 2019.2.0 (2019.08.08)

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.

Release 2019.1.0 (2019.02.27)

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.
