What is projection mapping?
● Using projectors to map light onto surfaces● Turns any 3D object into an interactive display● Use of motion graphics and/or creative coding to “replace” a surface● Can add motion to static objects
-
Types of Projection Mapping● Video Jockeying (VJ-ing)
○ Live events being augmented by projections - fully dynamic, controlled live, consists of
pre-programmed videos and combinations of
effects & effect overlays
○ Often interactive to music (ex. DJ’s and music festivals)
● Theatrical○ Preset projections and scenes are “cued” in set
order
○ Ex. dance scene backgrounds
-
● Static/Interactive○ A programmed display that loops or interacts
with the environment and viewers
● Video○ Segmented show is presented as a single fluid
video
○ Not interactive

Some Things to Consider When Creating Projection Maps● Viewing angle of audience● Size and shape of object/landscape/building● Location and environmental factors (indoors/outdoors)● Type of animated content

Turning a 2D Surface into “3D”
1. Scan and plot out the surface2. Skew and distort the 2D surface with specialized software
a. Ensure that content will look 3 dimensional when projected onto surface3. Develop the animated content

History● Was known as “video mapping”, “spatial augmented reality”, or “shader lamps”
before its current name● 1969: Disney’s Haunted Mansion Ride
○ Filmed headshots of actors with 16mm film and projected those images of their faces onto busts
