Whatever the content source is, you’ll also need a media server to play back the created content and manage onsite alignment and blending. Content production methods vary widely from analog stop-motion graphics to real-time rendered effects using 3D content tools.
The projection design will influence the overall resolution of the content, which can be produced using the same UV mapped 3D file. At this point, projection designers can design the optimum projector setup, choosing projector lenses and stacking configurations. Advanced tools also include simulation of light level (luminosity) to enable photometric calculations to understand just how much light will be visible on the object during the projection show.
This tool simulates the position of the projectors and projection mapped object to see the behavior of the projection pixels. When the UV mapping is complete, the 3D object file can be loaded into a projection simulation tool. The UV map defines which pixels of the 2D video file will fall where on the 3D object and is critical to modern projection mapping workflows. Courtesy of Andrei VisualsĪfter completing the 3D model of the projection mapped object, a process called UV mapping converts the object into a surface capable of “receiving video,” in software terms. Often laser scans are used to capture precise measurement and dimensions for the mapping. These 3D models will form the basis of the mapping, so it’s important that they are accurate. From there, you can use AutoCAD to create 3D models of the projection mapped objects. Key considerations are the location of the spectator area and of course, what object you want to projection map.
Festival of Lights on the Gendarmenmarkt, Berlin How It’s DoneĪll projection mapping starts with a concept. Head shots of singers were filmed on 16mm film and then projected onto busts of their faces to make them appear animated. One of the first public displays of projections onto 3D objects was debuted in 1969, when Disneyland opened their Haunted Mansion ride. 3D mapping is often used by advertisers and artists to add dimension, movement, and depth to previously static objects such as buildings or stages. Architecture, Engineering and ConstructionģD mapping technology–also called 3D projection mapping or spatial augmented reality–is a technology used to project a 2D or 3D object onto a display surface through spatial mapping.
