Projection mapping and audio visual equipment for The Big Game in Atlanta

GigRent was proud to provide projection mapping for buildings involved with “The Big Game” in Atlanta. One of those buildings was the Westin Hotel in downtown. The Westin Hotel was used as a canvas to show the Lombardi trophy in Atlanta using a cutting-edge technique called projection mapping.

Projection Mapping uses everyday video projectors, but instead of projecting on a flat screen (e.g. to display a PowerPoint), light is mapped onto any surface, turning common objects of any 3D shape into an interactive display. More formally, projection mapping is “the display of an image on a non-flat or non-white surface.” Projection mapping is when you project an image or video, large or small, onto an object that is not square or a standard size or standard image size. A flat screen that is rectangle and flat is a standard size, while round and curved is not. The Westin Hotel surface is curved, when that happens different beam lengths need to be taken into account. Multiple audio visual projectors are used for one image. Software is used to compensate for that curve, to ensure the image is still square. Mad Mapper is the projection software in this instance, it maps based off the images you load into the software itself. Specific shapes or textures are uploaded into the software which then tell the software how many projectors are being used and where they are located. Then, the software determines which projectors are actually shooting on the surface and which are sending the image to the surface you want to move. It will digitally manipulate the video or the image to compensate accordingly. The projection for “The Big Game” was a still image, but still required coordination between multiple projectors to sync and maintain the integrity of the image.
