Doing Projection Mapping¶
This document is a write-down for a workshop by Fabian Morón Zirfas @ the University of Applied Sciences Potsdam (Germany) as part of the seminar “Datenobjekte” (data objects) by Professor Boris Müller (a.k.a @borism on Twitter). We will explore the basics possibilites we have in the field of projection mapping. This is still work in progress, there might be 🐛, 🐉 and 👾.
- a computer
- a projector
- Processing Keystone library
- Processing Syphon library (Mac)
- Processing Spout Setup (Win)
Some of these are optional. Depending on which workflow you are going to use.

The gifs in these docs are created by transfomring a screenrecord with ffmpeg to a sequence. This sequence then gets transformed with ImageMagick to a gif. ffmpeg and ImageMagick can be installde using homebrew.
Install brew like discribed on their site. Then run:
brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools brew install imagemagick
You should be good to go.
