PROJECTION MAPPING INDUSTRY.
“Projection warping, also called geometric correction, is the process of digitally manipulating the image data to make it look accurate” “It’s also becoming achievable for more people to projection map with free software downloaded from the internet,” says Selwyn. “On the professional side, the computers needed to run software are vastly more powerful than they were five years ago,” he explains, hinting at a major Dataton software release later this year that’s concerned with 3D mapping. There are limits to how much canvas one projector can cover. For example, you can’t project on the 640 sq km surface of the Hoover Dam with just a single projector. In many cases, you will need multiple projectors as well as software for edge blending – to remove the visible borders of overlapping images – for a seamless viewing experience. Projector warping, also called geometric correction, is the process of digitally manipulating the image data to make it look accurate on the specific projection surface or shape. “We’re seeing a clear distinction between cutting-edge and entry- level applications from a technology, complexity and content creation point of view,” says Lieven Bertels, segment marketing, immersive experience, Barco. “A lot of the earlier work was makeshift, you pieced together a show from scratch each time for one particular space.” In the US in particular, this trend is driven by the need to make immersive
