I decided to use the plant in the tutorial as it looks like a simple object but it is in fact rather complex. The real takeaway from this whole workflow is how simple it is to create a mesh from photographs.
To illustrate the idea of applying the exact same workflow to other objects, I took photos of a very complex tree and this is what I got:
I also '3D scanned' a statue that turned out great with high-res textures:
The awesome thing about these scans is that both objects had lots of things in the background and 3D Sampler managed to generate an impressive automatic mask.
