Very beautiful and nostalgic, so well done. I used to live nearby and my favorite “urban” hike was going up Glen Canyon, up and down the two Twin Peaks, loop through Sutro Forest and then go back to downtown walking down 17th. Loved those weekend walks.

Ha yes love that loop, so strange to see someone else tying it all together! Not quite as good but when I lived in the sunset — grand view to golden heights along the ridgeline then down to Laguna Honda trails and up to twin peaks and out sutro forest to Parnassus.

Looking under the surface has its own charm

Ten television stations, three FM radio stations, and 20 wireless and mobile communications users (i.e. law enforcement agencies, taxi cabs, school buses, wireless internet, etc.) rely on Sutro Tower antennas to transmit signals over the air to the entire Bay Area.

For some reason it never occurred to me that Sutro was still a live radio tower - it’s such an SF landmark that I think I just assumed it was decommissioned or something.

This does not work at all on Android Chrome. The about dialog flies in super slowly, continually re-layouting the text, and there's no "small cube" and no way to dismiss the about dialog either. The background looks tantalising but maybe a little more testing is needed... (e.g. for the most common browser/OS in the world).

Wow surprising, do you have any console errors? I tested extensively in Android chrome. To dismiss the modal you can tap in the margin.

I'm not sure how to see console errors on mobile (without the remote dev tools anyway).

I tried again today and it's still really slow but I do get the controls this time so I was able to use it. Very neat!

This is on a Pixel 8, Chrome 113.

This is great but please implement mouse look! It makes it way more immersive and is the lingua franca of FPS interactions.

You can free look with the right mouse button

I’ve been to Atlanta. A hundred miles of suburbia is not an improvement and is actually a dystopia.

Dystopia usually conjures up a neon bright towers of an overwhelming big city. I've been to Atlanta too and I quite liked it. Low density, lots of green space, decent public transit (MARTA). Lots of interesting neighborhood variability.

Atlanta is beyond overwhelming big. It can literally take 3 hrs to drive across.

This means that SFH's can only become duplexes until duplexes are the norm. No, it doesn't; existing SFHs can, and have when allowed to, become duplexes, triplexes, and sometimes even quadruplexes without changing square footage at all , with doublin…

This is a general argument assuming units being arbitrary. Units should be effectively arbitrary, but every town will have different rules.

Well, no, it doesn't assume units are arbitrary, it assumes units are fixed square footage, which they are not. Under most regulatory schemes, there is a practical minimum size or a habitable unit, but a pre-existing area zoned for detached single-family units exclusively is unlikely to be comprised of single-family units that happen to also be the minimum square footage for a habitable unit.

Wow! I'd love to read a more in-depth blog post describing how to create one of these myself, and maybe even contribute my own splats to a collaborative library for iconic landmarks. I could see interactive splats being added to Wikipedia for popular locations.

Pretty much the same workflow as photogrammetry take a lot of images/videos and put them in one of the SOTA gaussian splatting tools.

San Francisco is just so beautiful. There's a serenity to it that I can't quite put my finger on. The way the fog waterfalls over the hills when you take the train in from the south... the view from Sutro. The gum tree trove near the tower.

This captured that serenity.
