Show HN: I 3D scanned the interior of the Great Pyramid at Giza

Is the main entrance actually opened/digged through? (I know it's not really needed, just curious).

It is not very clear from the picture outside. You can have a glance of the other side (as part of Descending Passage) as well in OP's tour, but again not clear, the view is blocked by something there.

I had spent few weekends in my attempt to automate the process of generating 3D model from pictures. The underlying issue and concern folks have with matterport is their lock in. You are free to upload images to it but not allowed to self host or use their resource to generate the 3D dollhouse.

The regular way requires to feed the photo into multiple layer of software. Example, generate a point cloud, create a mesh from it, clean up the mesh and port it a Fanwood to be consumed (unity. Unreal, etc) this is all manual.

I am genuinely curious how the folks at matterport are able to do it with next to no human input after feeding it 2d pictures.

In person those tunnels are quite claustrophobic. You have to bend over quite a bit and at the same time you're thinking that there's thousands of tons of rock above you.

Quite a few people in my tour group turned back because they couldn't handle it.

Visited in 1995.

Thanks for the amazing work! Here are my notes:

1- Actual surveying of the site was a bit annoying. On one hand, I wanted to scan everything and look at every detail. On the other, I didn't know where I was and didn't want to miss out by my depth-first approach. The automatic surveying routine (clicking next) moves the camera way too fast. Also I guess it doesn't present everything we know of the site. For example I wanted to have a more clear look at the shafts.

So A) provide a minimap for every detail we know of the site to make idealists of us, happy :)

B) slow down the speed of auto-surveyor.

I experienced these same technical problems while traversing the Perspolis site: https://persepolis.getty.edu/

2- What's with the utility wiring in the King's chamber? Is it customary in archeological sites? I thought it should have been done more neatly.

Also, do the "cosmic ray detectors" work by battery power in those wooden boxes? Is there a rule that scientific instruments should be in wooden boxes?

3- How do we know what the main purpose of the Great Pyramid was? Why were the chambers named as King or Queen's chamber when we didn't find any mummies or hieroglyphs inside?

This question especially becomes important when we don't know what the purpose of those clear-cut shafts in chambers was.

4- As an archeologist, what do you think of the works of Erich von Daniken or the claims that ancient human technology couldn't have cut those clear cuts or moved those giant stones?

5- Before seeing this, I just woke up early from a nightmare. I rule out most of it due my brain mixing my personal experiences of the day and university. But, the strange part of that dream was that at the end of it, someone trapped someone else (like in a dome wire-frame cage that is used in catching birds) , and I heard a serious stern voice ordering him to "dig". Next up I woke up and saw this on HN, deciding to have a virtual visit of the internal chambers of the Great Pyramid. Phew! What a coincidence!
