Basic implementation of meshroom importer. If you have sphisticated node three it will use only the first nodes from the file. Addon assumes you did compute each stages/nodes, and the output is same.
Important note: For sparse point cloud to import you should change in
StructurefromMotion node output:
Inter File Extension to
File > Import > Import Meshroom or [F3] Import Meshroom. Then select Meshroom working file .mg.
Additional option: by searching [F3] for
Meshroom update cameras, you can copy settings from active camera to all meshroom cameras.
Big thanks to Jakub Uhlik for sharing Point Cloud Visualizer to view point clouds in the addon.
