So, to playback video and still content into MadMapper, you use programs that support Syphon. Think of it as a system of internally routing video signals out of one app into another app as an input. It relies on a protocol called Syphon, which allows video applications to share their entire video output with another app in real time. While it lets you projection map, it doesn’t (fully) have the ability to even playback videos. However, MadMapper is just a means to an end. Our first year, we started on the first day with a set of 100 white canvas squares, and on the last day, we projected onto a large white curtain, adding in environmental projection to the mix. We’ve used it the past two years at SALT because it allows us the ability to quickly project video onto one surface, then change or modify something, and project it again. It allows you to effortlessly curve, bend, and warp projection onto any object you can think of, no matter the shape or size.

If you’ve never played with the app or heard of it, go download the demo, find a small projector, some sort of random object to project onto, and carve out some time, because it’s really fun to play with. It’s an app that was created to facilitate the world of projection mapping. What we used, which is one of my favorite tools to play with, is a fun app called MadMapper. The great thing about projection right now is there’s an amalgam of software, hardware, and ways to accomplish this, all with their own pros and cons. In 2013, we explored using projection to map video onto the canvas panels of our set. Two of my favorite technologies that we’ve implemented over the years at SALT have been the use of projection and LED strips. It’s pretty hard (for me, at least) to think back to the year 2000 or so when most of us didn’t have-or even know, really-what a moving light was, how we could ever afford a projector, or probably thought that a line array was some sort of math-geometry jargon. Technology in the church has come a long way, as I’m sure a lot of you know. If you were at SALT13, you had a chance to see this pixel mapped set first hand. Lets go back to our first SALT Gathering and see what the pixel mapping and projected set design looked like during SALT14.
