Ever since I was a boy growing up on a farm covered in rocks, I’ve wondered about the possibility of using a computer to calculate a pile of rocks into a stone wall.
Geometric Reassembling
The process would work something like this:
- Each rock is scanned 3 dimensionally and marked to identify top and bottom
- Rocks are tagged and stored with an easy access and identification system
- The 3D rock images are placed in a database
- The parts of a building design that could use stone construction are rendered into a 3D image
- A computer programe analyzes the rock 3D images and calculates the best sequence to fit into the design with options to have: bigger rocks nearer the bottom smaller at the top, have stones in a flat lying position, 5mm mortar gap, etc
- The builder would then use an onscreen display during construction.

Some development is taking place, see link,
