The photo of the wall in the article is obviously digitally altered, just to the left of the person walking. The rocks change into uniform smooth grey, and it doesn’t match the reflection in the water. Is it supposed to be the digital plan of the wall vs the real thing?

If you zoom in you can see that it's a polygon like mesh. It's certainly supposed to be how the rocks are represented in the system.

Yes, I think it's an artistic interpretation of a digital model of the stones - how the autonomous system sees them.

It absolutely matches the reflection in the water - you can see the hard hat of the person and the colour transition.

The change in colour will be the result of a change in source of boulder. The whole point is that they are "recycling".

where were the wireframe mesh rocks sourced from?
