Definitely one of the better implementations I've seen using Matterport's SDK, nice work. Did you use the Pro3 as the capture device? Before the collapse anyway!

Thanks, and I was still on Pro 2 + BLK 360 unfortunately. Haha, thankfully all the cameras survived and made it home, just muddier.

This is very cool! Can you share the technical background you've used for creating the 3D reconstruction? Like software packages, or algorithms used. Are we looking at the result of packages like OpenSfM here, or COLMAP?

Onsite I used the Matterport capture app and Matterport Pro 2 and BLK 360. For the web version linked here, I built on top of the Matterport SDK with Three.js https://matterport.github.io/showcase-sdk/sdkbundle_home.htm...

So in the virtual tour, you're seeing 360 imagery from the cameras and a lower resolution version of the 3d capture data, optimized for web. The lower res mesh from the scanner is transparent in first-person view mode so users get cursor effects on top of the 360 image.

For film, PBS sent out a documentary crew, and they wanted me to render some footage of the full tunnel system, so I exported the e57 pointcloud data from Matterport and rendered the clips they needed in Unreal. It should be coming out soon with "In the Americas."

Oh man, the BLK360 can be a frustrating (albeit incredible) device even in the best of conditions, let alone this. Glad to hear everything survived!

I mostly use the Pro3 now but did a big chunk of this Georgia Tech scan with the BLK: https://my.matterport.com/show/?m=PB8FgAyyjHx

Does anyone know if there’s a simple solution to generating NeRFs from a continuous all directional camera (like a GoPro Max). It would be fun to make an explorable universe like that.

You should be able to do this with nerfstudio: https://github.com/nerfstudio-project/nerfstudio/ I've done it a few times, you can test 3d Gaussian Splatting also instead.

Haha, yeah I know what you mean. I had to do the exterior with the BLK for only a few hours each morning before it overheated.

That's an impressive huge capture!
