Do you like to play with shadows? If so, you’ll love projection mapping. That’s when you use a computer projector to create a cool effect on a ceiling or building. Let’s learn some more.
1. What is projection mapping? According to http://projection-mapping.org/whatis/ you learn that it’s simply pointing a computer projector at something, to paint it with light. You can play a scary video on your house a Halloween, or make Santa’s sled move across your ceiling during a concert. The possibilities are endless.
2. What do I need to get started? Two things: a computer (or tablet) and a projector. Also handy — a dark place, a light colored surface, extension cords, graphics adapters and permission from your neighbors. Remember that projection mapping can draw a crowd, so you’ll want to make sure that everyone is safe. Read more about the history of projection mapping here: bitly.com/2ksPhCc.
3. What software do I need? There are many specialized programs that let you carve up your space so that the light matches your target. See http://projection-mapping.org/software-2/ for a good list. You can also use common presentation software like PowerPoint or Keynote. It helps to use highly contrasting images. Experiment with the slide transitions.
