Currently when photographing a scene you can take 100 - 200 photos, upload to the service, then wait 3 - 4, sometimes 12+ hours and view the result only to find you made some mistake or the lighting for some photographs was off.
It would be great if there was a draft mode (that runs offline w/o cloud) that lets you view the mesh offline before uploading. Several other photogrammetry tools (agisoft photoscan, zephyr 3D) support this.
