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

• 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.
