Purr Data (2020)
This project is the work that was done under Google Summer of Code 2020 a.k.a. GSoC for organization Purr Data. The project idea was to make the native Purr Data run in a web browser by adding a WebAssembly target and HTML5 GUI framework.
Purr Data a.k.a. Pd-l2ork 2 is an improved version of Miller Puckette’s Pd.
Pd (Pure Data) is a graphical data-flow programming environment that is geared towards real-time interactive computer music and multimedia applications. It is a full-featured open-source alternative to its commercial sibling, Cycling74’s Max.
Purr Data serves the same purpose, but offers a new and much improved graphical user interface and includes many 3rd party plug-ins. Like Pd, it runs on Linux, macOS, and Windows, and is open-source throughout.
The goal of this project is to make the graphical programming environment Purr Data run in a web browser so it can be more accessible to users.
