That's beautiful. It's just begging for translation overlays on the exquisite wall detail.

Before High Fidelity VR shut down they were doing tours with an Egyptologist tour-guide of another tomb which was really cool.

High Fidelity missed the Coronavirus WFH opportunity by only months. They claim to still be working on something new but, wow, its hard to think of a case of worse timing.

For some reason, I am getting motion sickness while clicking around. But it's really detailed and cool.

Me too. Wonder if a VR version would be less nauseating.

It's probably the smooth acceleration/deceleration. I bet if the movement was a straight ramp instead of a smooth curve you'd feel better.

The picture/texture quality is mind-blowingly amazing.

Imagine if video games had textures this high-definition!! They'd look so insanely good. And it's not like our present-day technology/GPUs can't handle it. It's probably more that video game makers don't want to spend a huge amount of money on artists and graphics people to create ultra-high-definition textures...

Earlier quoted context omitted.

Seems like a combination of 360 photography and off-the-shelf photogrammetry algorithms. Don't know if there is some secret sauce needed (not obvious from the content that there would be).

Well, do you know where these shelves are? I'd be interested in photogrammetry software to reconstruct 3D models of environments, mostly to plan construction or aesthetic changes to buildings or surroundings. This is for home use, so I don't really need fancy texturing, etc. But having it reconstructed from a smartphone video feed would be a must. I looked for open source software a while back, but didn't really turn…

If you want to investigate free software options then may I suggest you look into Visual SFM (http://ccwu.me/vsfm/) or AliceVision MeshRoom (https://alicevision.org/). I haven't used MicMac, might be good as well.

I tried several years cheap approaches as you requested with no luck. Then I upscaled my gear.

I've used Agisoft's Metashape with great success (https://www.agisoft.com/). The cheaper license offers really good functionality as is.

DICE has published a pretty good intro into how to use it to capture photogrammetry data in https://www.ea.com/frostbite/news/photogrammetry-and-star-wa....

You do want to have a good camera for good results. My Mavic Pro's (a drone) 12 MP is barely tolerable. With Sony Alpha 6000 (24MP) and good lens, the results are fantastic. Camera phone can work, depending on the capabilities of the camera, but I would use photography and not video material - the images from photography seem to be better quality than frames extracted from video (YMMV).

If you have the patience to collect the image material, the results can be really good.

For example, as a hobby I've been collecting photogrammetry models from an office building being built near my home:

https://sketchfab.com/3d-models/hatsina-20200426-bdd04329548...

So what you see there is the model as presented by Sketchfab. The textures and model are coming from Agisoft Metashape, Sketchfab is just used as a platform to display the model for public viewing.

The data closer to ground is captured by my Sony Alpha 6000 while the data from above is from drone. I'm happy with the portions of model based on 24MP DSRL images but the drone based material does loook "melted" occasionally.

As a reference, the source data for that model was roughly 800 images.

The data the photogrammetry algorithms consume are coming from the pixel data. More pixels, the better the outcome. Roughly, the resolution and precision you can expect from the result mesh is equivalent to the pixel density of your source material. The algorithms don't invent anything that they can't see in the pictures. This means, that for example for columns you need to take 360 of tens of images around each column to make them appear ok in the model.

Striking how _different_ this is from the pyramid of Giza. For this one, every inch covered with illustrations and hieroglyphs; for the great pyramid, completely bare, devoid of images.

To be fair it might as well have been flashy on the outside, but erosion of the surface exposed to the elements (and sandstorms) is very high. We supposedly already know that it was covered in limestone, and some sources even mention looting of the limestone to build forts

There are a load of these that I found - source https://twitter.com/tourismandantiq https://my.matterport.com/show/?m=d42fuVA21To https://my.matterport.com/show/?m=QaGBAsT6yg4&mls=1 https://my.matterport.com/show/?m=ui3dfrQDqB2&mls=1 https://my.matterport.com/show/?m=xmDbt2rfa82&help=1&brand=1... https://my.matterport.com/show/?m=PKxweZaPG3P&help=1&brand=1... https://my.matterport.com/show/?m=zBpDdPqxTKz https://…

Thanks for posting these! I made a few of them. I'm glad people are enjoying them! To keep adding to the list, here's the set I worked on: Islamic Art History and Architecture: Bab Zuwayla gate, museum, and minaret: https://my.matterport.com/show/?m=YZXMPtiuR9D ( http://arce.org/ ) Faraj Ibn Barquq Mosque: https://my.matterport.com/show/?m=UCDj6MdbCes ( http://arce.org/ ) Aslam al Silahdar Mosque: https://my.matterpo…

Thank you for this, and all of your work. There are many places you've shot and produced like this that we will never be able to get to, and this is a true joy to spend time in.
