How did you manage to scan the whole thing?

Great, what software are you using to edit the point cloud?

Yes- it's MAGIC :))) ...but you see the limitation on a closeup. Would be great if we can somehow limit the free camera movement for the viewer like adding some primitives as collider (two boxes or spheres: inner collition / outer collision) or a general min/max distance

just 13Mb, how could it be?

You are a magician schindelar. The quality of this model, especially given the modest size is breathtaking!
