Augmented Reality is great for helping people get a feel for a product without actually getting their hands on it. We’ve all seen some great examples, where you hold a marker in your hands and up pops a 3D rendering of the product. But what happens when the product in question is several hundred metres tall?

This didn’t stop André Fogaça from Rossi construction in Brazil, who figured that if a small printed marker can be used to show a small 3D model then he’d simply scale up the marker to show a much larger model. In this case the the ‘Fibrasa Connection’ development – a huge tower block!

So this is just what he did, printing an enormous marker (over 10 metres square) and placing it on the site where his company was due to build the tower. He then hired a helicopter to fly round the site, and used his web-cam equipped notebook to run the AR software. Great thinking André!
