The Photoscan edit tool has limitations since you can not choose to edit a sub-portion of the point cloud if it is a complicated, self-obstructing object. Others (Darko, Patribus) on this forum have noted this before me. Apparently there is no documentation on the oc3 file format available. Lets just do this in external programs for the time being, but:
While we already can export the dense point cloud, it would be extremely helpful to reimport it as ascii table or ply format.
I would rather not use
meshlab an import a mesh back into photoscan.
