Category: Projection Mapping
Projection mapping, similar to video mapping and spatial augmented reality, is a projection technology used to turn objects, often irregularly shaped, into a display surface for video projection. These objects may be complex industrial landscapes, such as buildings, small indoor objects or theatrical stages. By using specialized software, a two- or three-dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on. The software can interact with a projector to fit any desired image onto the surface of that object. This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative.
VJ’ing or VeeJay-ing (video Jockeying)
VJ used where live events are augmented by (often interactive to music) projections which are fully dynamic, controlled live, and consist of pre-programmed videos and combinations of effects and effect overlays.
Theatrical is used where projections are preset and scenes are “cued” on demand, usually in a set order, in conjunction with dance or onstage performance, often interactive.
Interactive types is used where a display is set up and loops or interacts with the environment and viewers via programming.
Video is where a generally long segmented show is present as a single fluid video that is not interactive and plays from beginning to end.
By using a pre-production process during which images are fitted onto a 3D graphic model of the building, the same images appear to wrap themselves around the physical features of any structure. They give the appearance of being painted on and part of the same structure even though they are not.
This process can also be used on a smaller scale to project virtual images on anything from a mannequin to a car to completely change their color, structure and appearance.
Projection Mapping has fully evolved since its first outings in the early 2000s when it was used to project visual-art and enhances live-music shows. It can now be used by production companies to incorporate the telling of entire stories, by using animated visuals and music to produce cinema style action and narratives.
Projection mapping can turn buildings, walls, floors and even common objects into something truly magical. There can be two types of projection mapping, 2D and 3D.
The device that is used to project rays of light, especially an apparatus with a system of lenses for projecting slides or film on to a screen. Widely available in the market with many suppliers and systems.
Central Control Unit / PC
Artwork that is computer generated, in which case software controls the laser exposure of the image file, one pixel at a time. (Pixels are the individual dots that comprise a graphic image on a computer screen or printout.)
CASE (COMPUTER AIDED SOFTWARE ENGINEERING)
CASE is the use of a computer-assisted method to organize and control the development of software, especially on large, complex projects involving many software components and people. Using CASE allows designers, code images. It may also serve as a repository for or be linked to document and program libraries containing the design requirements, design specifications or detailed code specifications.
Techniques include speech recognition systems that translate a user’s spoken words into computer instructions, and gesture recognition systems that interpret a user’s body movements by visual detection or from sensors embedded in a peripheral device such as a wand, stylus, pointer, glove or other body wear. Products which are trying to serve as a controller of AR headsets include Wave by Seebright Inc. and Nimble by Intugine Technologies.
The computer analyzes the sensed visual and other data to synthesize and position augmentations. Computers are responsible for the graphics that go with augmented reality. Augmented reality uses a computer-generated image and it has an striking effect on the way the real world is shown. With the improvement of technology and computers, augmented reality is going to have a drastic change on our perspective of the real world. Computers are the core of augmented reality.
a lot of the software used for creating content is cross platform, Mac & PC mainly. Popular tools of the trade include, Photoshop, Illustrator, After Effects, & Cinema 4D, while there are many more, these 4 and others like them should give you a large enough playground to create custom visuals.
Example – Optoma Projection Mapper
The Optoma Projection Mapper is a Android, iOS, and Amazon app that brings powerful projection mapping to almost any device. Optoma Projection Mapper enables you to beam multiple images and video onto 3D surfaces to create digital art – known as projection mapping. It’s a completely new way to use your home projector to create unique light displays for the same engaging experience you see at large events. Project onto any surface in your home, party venue or event space.
Example – Madmapper
Madmapper is an advanced tool for video and light mapping. Fast and user-friendly tool, adaptable to a variety ofuses like architectural projection, art installation, and stage design. For Mac and PC, madMapper makes a seemingly complicated setup simple and easy to realize.
Example – Resolume Arena
Resolume is a performance suite for video artists and VJ’s. Arena combines all of the functionality and features of their “Avenue” VJ software along with Projection mapping, projector blending, 3rd party plugins, and SMPTE sync. They are now on Version 6 with new enhancements to their projection mapping toolset as well as DMX / Lumiverse / Artnet support.
