Factory scene

[MoralesSan]

Hello everyone,
I would like to create a scene like the factory that is shown right at the beginning of the readme.md file on the project's home page.
How was this dataset produced?
In the documentation it is said that colmap wants a series of photos that point inwards toward a central point of interest, but for an open interior scene like the example, the camera must point in all directions, inward AND outward.
Would it be possible to have access to the factory dataset to learn?
Best regards,
L
