There's an interesting decaying tree stump in my back yard. I thought it was a good candidate to try out some photogrammetry! The mesh is still very complicated even after decimating the model quite a bit.

I'm astounded at how well this technique can work. It even captured the bark peeling away. Printed example was done at 100%, I'm sure it would scale up well. Reuploaded fixed model with bottom cut oriented level to the build plate (oops)
