What This Means for Your Design

Imagine you have a 3D model of a building on your computer. Instead of just looking at the screen, this research shows how you can use a projector to shine that 3D model's details onto a real, small-scale model of the building. This makes it easier for everyone working on the design to see and discuss it together.
