These look great! What strategy did you use to do the transitions?

It works as you described: Texturing the mesh "live" as you move through it. It does use Three.js as a base, but needs custom shaders to make it 60 FPS.

Very cool.. bravo -- it looks so good

It's something we have to be careful of while working on site! We're really careful around the rooms that have mercury in them--there are few that I didn't put in the guide also. I was wondering about this too: they've found high levels of mercury in the water supply at Maya cities and believe now it contributed to the eventual collapse: https://arstechnica.com/science/2020/06/mercury-and-algal-bl...

> “The drinking and cooking water for the Tikal rulers and their elite entourage almost certainly came from the Palace and Temple Reservoirs,” wrote Lentz and his colleagues. “As a result, the leading families of Tikal likely were fed foods laced with mercury at every meal.” This makes me think: what if today's rulers are being poisoned by something making them act like idiots?

It could be that there is something making our leaders mentally ill, or it could be that only the mentally ill think that they should be leaders.

This is great use of the technology. There should be scans of all our national monuments, world wonders, etc. So much better a use for the tech than just Redfin.

Popping my comment cherry here! I’m a 3D artist that is currently encountering staunch resistance of generating 3D models from drone captured photogrammetry of historically protected sites in Pennsylvania, USA. I’ve had resistance from the state and county level in pursuing take off and landing permission at historical sites.

> digital historic preservation

When I hear "digital" I don't exactly associate long-term preservation with it. Do you also have a strategy for the "digital preservation" part? Websites don't live long. Storage media don't last long either.

Should such a program be made together with a partner that has a strategy for long-term (outlook of centuries) storage of digital content? Because otherwise I don't see the "preservation" aspect. The monuments will likely survive all the digitized data created from them, easily.

It's not just the data, but also ways to use it. Imagine this was done twenty years ago and it was all saved as Adobe Flash media.

I think preserving the digital media plus ensure that it will still be usable (hardware and digital format) is a monumental effort, in comparison creating the digital representation is not the hard part.

Have you looked to see whether there is a local archaeology or social history society in your area that you could join? They will have individuals involved who are already used to dealing with property owners to arrange research projects, and you might be able to accompany them on the trips they organize. For reference, the archaeological society in my region serves around 400 square miles and typically organizes a l…

I’ll have to look into regional historical societies. The county wide historical group has not been keen on allowing access to properties without a justified end goal other then “3D model”.

Which to be fair is a step I’ve still yet to figure out other then having models hosted on sketchfab.

I’m starting to visit in person farmer markets that exist on land with over 80+ year old histories and structures.

The personal educational avenue is another great option I haven’t considered. I’ll keep this in mind.

Here is a 3D model of a carriage house built in the late 1800s that I processed from drone photography. https://skfb.ly/oW8v7

This was from a public park so no permission was needed.

This is great feedback. I’m still at the content creation stage, aerial and terrestrial photogrammetry to produce 3D models. Hosted on sketchfab.

I really haven’t figured out a solution to host 3D models that isn’t tied to a web based private company. I.E sketchfab.

Curios if there could be an avenue of resin 3D prints of the 3D models. I always seem to loop back to “why does someone want/need this?” Which may in turn be the reason for state/county property owners refusing permission to access property.

The digital capture is indeed the easy part at the scale I’m working in - thanks again for this insight

> staunch resistance Why?

PA restricts drone take/off and landing to only 6 parks in the whole state.

So for example, Washington’s crossing state park with its 3.7thousand acres, restricts drone/take off and landing by state law.

I’ve politely reached out to the park, and being a federally licensed commercial pilot with insurance coverage doesn’t pry that jar open.

The airspace classification is the limit, so I can fly over as much as I want - problem is all surrounding property is privately owned and I need to maintain 3 statue miles of visual line of site.

^ All of the above makes it impossible to capture up close aerial imagery of colonial period houses and barns for photogrammetry.

Smaller single structure county owned properties only hand out photography permits if events are being held, or the photography/videography is associated with a production company.

I may need to expand my municipal and county outreach further away from the county I reside in. Which is a shame since there are some beautiful historically preserved farmlands and structures in my home county.

Hey I'm really sorry! It's really hard. My photo permissions at Giza took two years to secure. My only advice is to keep showing up in person and hang in there--I feel for you!

That’s some incredible perseverance from you! In person is the right move though. Getting FaceTime in with groups or people who are part of the process does seem to make the best headway.
