Projection mapping - visual display technology with light!

With the recent SEA GAMES held in Singapore, many have witness the vivid and vibrant display of lighting graphics on the field of Singapore Stadium!

Today we would like to share what we know of the technology. The name of this process is 'projection mapping' or 'video mapping.' It is a form of augmented reality. That is to have our eyes and mind see an image although it doesn't really exist in real form.

This method is often used in our festival of lights, Arts nights, Asian Civilisation museum and even our Singapore National Museum previously. The basic application is have video lights projected to a wall surface. While the video moves, it is often that viewer is able to distinguish the real surface and the video effect.

A highly skilled lighting videographer will be able to go beyond just using the facade of a building as a display screen. They should enable the whole building to come alive through manipulating the projection lights.

(E.g. Viewer is able to see and sense a building jumping out of its' skin and cascading towards themselves. That sub-conscious sense may make a person move themselves to avoid being 'hit' by the building. Such an experience is the real power of projection mapping and should be considered the real success of interactive visual display technology.

As a lighting consultant, we would think that knowing the capability of your hardware and the environment is 2 essential criterias for a successful video display show!
