This workshop will revisit the seminal works of the pioneers of generative art from the 1960s and 1970s: Colette and Charles Bangart, Frieder Nake, Georg Nees, Michael Noll, Vera Molnár, and others. At a time when computers and plotters were confined to research laboratories, these artists paved the way for new forms of creation using algorithmic material.

"We think the image. We don't make it.

When we think the image, we always think infinitely many images. That's absolutely new. The algorithmic artist is thus a totally new kind of artist."

— Frieder Nake

Thomas recoded and played with Frieder Nake's Walk through raster algorithm.

Olivier jumped into the realm of cubes edges by recreating one of Manfred Mohr's Cubic Limit.

Nicolas was the James R Warner emerging man and started to recode ArcLink by Auro Lecci.

Swann played with classic Georg Nees' Schotter, Harold Cohen's "Three Behaviors for Partitioning Space" and Roger Coqart's Structured Square - Inwards.

Marine created a new artwork from Aaron Marcus' Untitled 3.

Matthieu played with a custom algorithm and plotted it with a Roland DXY plotter.

• Visual Studio Code
  • p5.vscode
    It helps you create p5.js projects in Visual Studio Code. It also includes autocompletion, a simple tool to browse and install third-party p5 libraries, and the Live Server extension.
• vpype
  Swiss-Army-knife command-line tool for plotter vector graphics
• Inkscape
• AxiDraw software installation
• HTTP server that comes with this repository to perform various tasks through an API :
  • resize svg files with vpype.
  • transform svg to hpgl with vpype.
  • drive AxiDraw plotter.

This is not mandatory to install and run it for this workshop, though it is useful for easily manipulating svg and generating hpgl commands.

python environment is needed to run the server.
Note for Mac users : if pythondoes not work, replace with python3 in the following commands.

First we are going to create a virtual environment for the server. In a terminal type the following commands :

# Replace [path] with the appropriate location on your system
cd [path] 

python -m venv .venv

Then activate the virtual environment :

MacOS / Linux

source .venv/bin/activate

Windows

.\.venv\Scripts\Activate.ps1

Once the virtual environment is activated, install the project’s dependencies listed in the requirements.txt file:

pip install -r requirements.txt

That's it ! You should be able to run the server now.

python ./server.py

If everything went fine, you should be able to open http://127.0.0.1:8080 on your browser and navigate into the examples.
