Generative Gestaltung is a very nice archive of processing code which offers direct access to all processing source codes described in the authors book of the same name.
This is from the page: “The book »Generative Gestaltung« deals with the creation of images by using codes. An image is no more created manually but through a visual idea which is translated into a set of rules and then implemented in a programming language in the form of source code. The consequence is that such a program can not only create a single image but also completely re-design visual worlds by changing the parameters.”
I used code P_4_2_2_01 to create the images on this page.
Great work by the authors.
