For Sydney siders, probably the most visible and obvious use of ‘Projection Mapping’ that we would all have seen, would be the lighting and visual effects thrown onto prominent buildings around the city during the Vivid festival in May/June each year.
In short – ‘Projection Mapping’ is a technique using specific software and other projection technologies to warp and blend images so they fit perfectly on irregularly-shaped “screens” – which can be anything from buildings & interior spaces to objects or even natural landscapes. The technique uses everyday video projectors which map light onto a chosen surface, turning common objects of any three dimensional shape into interactive displays.
The projected image is mapped in such a way that it interacts with the geometry of the projection surface and space – you don’t need to make physical changes to the structure of the target object. The projected image will mask and change the look and visual shape of what you are actually projecting onto.
The result is that practically any surface can be changed through dynamic visuals, throwing the onlooker into a ‘virtual’ world using the illusion of colour and light. Continue Reading
