This is yesterday's news. It's from a months ago, but it's one of the most most amazing examples of the blending of the virtual world and the real one. For the 10th anniversary of RalphLauren.com, this light show was projected on the face of the RL store in NYC. This video is exactly as it would have appeared watching from across the street. No digital effects have been added. This is just light on a building on 5th Avenue in New York City!
If you haven't yet been exposed to some of this cool Digital projection, it's called 3D Video Mapping and here's how it works.
- What is 3D Video Mapping or 4D Projection? An everyday object like a building is used as a canvas and projected upon with very high-quality, digital projectors. Just like a movie is sometimes projected on the side of a wall. But here's where it gets tricky. Instead of projecting just against a flat and plain section of the building, the entire object is scanned and a computer model of the building is created. With the precise knowledge of where every single window, door and brick is placed and exactly how the light will reflect off of cracks and crevasses of the building's geometry, a movie is created that makes it appear that the static object is actually coming to life.
3D Video Mapping or 4D Projection is another great example of Technology that is Changing the World.
