3d scans and NeRF from Bangkok

Sometime in 2019 I travelled to Bangkok with my team for a documentary project. While there we went on a boat ride through a river canal and passed a lot of old and new river front houses.. each had a nice jetty or balcony like structure over the water. At first I was shooting stills, then realised that if I shot slow motion video footage.. I might be able to generate photogrammetry data from them. Later that day at the hotel room I stayed up late trying to get it to work. It did'nt not on any of the apps or software I had been using for my other photogrammetry projects. 

Then last night I discovered Luma labs ai NeRF solution that runs in the browser. 
Here are the results.
Original footage:

NeRF:

This is the panorama you get from Lumalabs

And here's the model


Heres an mp4 of the NeRF (until I find a better way of sharing these)


Heres a low poly(they have a higher poly version as well) 3d model:

Cyberpunk Catbed

Did a scan of our cat Pinku the other day while she was fast asleep.
This is what I did with that scan

The original scan had some bugs because the lighting was suboptimal, so large chunks were missing.

I took it to Blender to explore some repair techniques, but woundup building this contraption around it.

Heres the finished model..

You can also try it in AR with Snapchat -

You can also try it in Instagram with this code:

Heres a video of the process I followed to use the 3d scan of my cat in the model. It covers cleanup and using the decimate modifier to optimise the geometry.

3d scan - Stump

A tree stump we pass on our dog walk route. Its of a tree that had been eaten up by termites. Was chopped down before it damaged powerlines.. but it actually broke in this uneven way, since it was hollowed out by the bugs.

Scanned with Scann3d but the scan failed.. so I ran the same photographs through Meshroom and got these results. Cleaned up and decimated(reduced detail) in Blender.
