Rutt-Etra-Analog Video Synth v2

Click to view see it in action

This repository is a newer version of Rutt-Etra-analog-video-synth-implementation uploaded in 2015.

RE-Viser is a software implementation of the amazing Rutt-Etra analog video animation synthesizer from 70s. The Rutt-Etra analog video animation synthesizer was co-invented by Steve Rutt & Bill Etra as an analog computer for video raster manipulation. RE-Viser is written on C++ using open-source library openFrameworks. The application has built-in GUI (Graphical User Interface) to create Rutt & Etra Analog Video Synthesizer style visual effects on imported image/video files. This is an ongoing open-source project. The source files and former beta releases of the application can be downloaded from my [github.com/alptugan] account. I’ve been using Re-Viser on my personal audiovisual performances and updating the source codes time to time. Currently RE-Viser is only available for developers, not suitable for end-users.

The code is still a little bit dirty and undocumented. Basically, the app has three modes; sitll image, moving image & video grabber modes. You can switch between the visual input modes setting the mode variable in testApp::setup() method.

Features

  • Control over Korg Nano MIDI device v1. To enable the remote control uncomment the following line in the header file;

    // Uncomment the foloowing line to enbale midi - Input

    //#define KORG_ENABLED

  • Enable load sound and play

  • Load still images like .jpg, .png, etc.

  • Load video files .mp4, .mov, etc.

  • Enable built-in/external webcam input

  • MIDI device input (Currently only Korg Nano Device is supported. However, if you are a developer, you can easly map your physical device via ofxMidi addon.)

  • Export the generated visual as .jpg file

  • Shader effects with ofxPostGlitch

  • Record and load 3D space camera actions

  • Convert the imported media to 3D mesh and view the generated image with virtual cam in 3D space.

  • Keyboard interaction

  • GUI interaction

Dependecies

  • ofxCameraMove
  • ofxFFT
  • ofxGui
  • ofxKorgNanoKontrol
  • ofxMidi
  • ofxMotionBlurCamera
  • ofxOsc
  • ofxPostGlitch
  • ofxTweener
  • ofxXmlSettings

Todo

  • Execute main alogrithm in the GPU via shaders. Any suggestion or help are highly apprecieted.
  • Improve user interaction. Camera movement can be adapted to ofxTimeline.
  • Finish documentation.
  • Enable sound reactive mode for loaded sound samples or/and microphone input data
  • Create Enum structure for mode selection.
