Doing Projection Mapping

Introduction

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 👾.

Prerequisites
  • a computer
  • a projector
  • Processing
  • Processing Keystone library
  • Processing Syphon library (Mac)

Creating gifs

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.
