Originally initiated in 2001 by Casey Reas and Benjamin Fry, both of whom were part of the Aesthetics and Computation Group at the Massachusetts Institute of Technology (MIT) Media Lab, Processing has since evolved into a globally recognized platform for visual programming and digital artwork creation. This article delves into the core aspects of Processing, tracing its origins, evolution, and current significance within the broader programming and creative communities.
Origins and Development of Processing
The story of Processing begins at the MIT Media Lab, a hub for interdisciplinary research where the intersection of art, design, and technology has often sparked innovation. The vision behind Processing was to provide an accessible programming environment for artists, designers, and educators who lacked formal computer science backgrounds. Reas and Fry, leveraging their expertise in both art and computation, sought to create a language that would simplify the process of visual programming and allow for immediate visual feedback—a critical feature for those involved in art and design.
In 2001, Processing was born from the idea of creating a platform that allowed non-programmers to engage with programming concepts. By focusing on visual feedback, the language could demystify the often intimidating aspects of programming, making it more approachable for users with no prior experience. Processing’s open-source nature also ensured that it would be continuously developed and refined by a global community of artists, designers, and technologists.
Processing’s foundational aim was to create a “visual language” for creative work. Drawing inspiration from Java, Processing offered a simplified syntax, designed to make it easier for users to create graphics, animations, and interactive designs. As a result, the platform quickly found its place among educators, digital artists, and those engaged in creative coding. Its intuitive nature made it an ideal tool for art students, designers, and anyone interested in learning programming through a visual medium.
Features of the Processing Language
Processing is distinguished by several key features that make it particularly suitable for artistic and creative programming. The language is built on Java, but it has been simplified in various ways to improve accessibility and ease of use. This simplified syntax makes it possible for beginners to write code quickly and see immediate results, such as visual representations of their work. One of the key advantages of Processing is its built-in graphics capabilities, which allow users to create complex visual elements with minimal coding effort.
Visual Feedback and Interactivity
The most prominent feature of Processing is its ability to provide immediate visual feedback. This aspect is crucial for creative work, as it enables artists and designers to experiment and adjust their code in real-time. Users can manipulate shapes, colors, and even complex animations without having to worry about intricate programming details. By updating the visual output as the code changes, Processing empowers users to focus on the creative aspects of their projects.
Additionally, Processing supports interactivity, allowing users to incorporate real-time user input into their projects. This includes mouse clicks, keyboard presses, and even webcam or sensor data. Such interactive features are vital for designers working on installations, games, or interactive art pieces, further broadening the scope of what can be accomplished within the environment.
Simplified Syntax
Processing’s syntax is intentionally designed to be simpler than Java’s, making it accessible to those without a programming background. For example, instead of dealing with complex object-oriented concepts, users can start by drawing basic shapes, controlling their movement, and gradually moving on to more complex tasks like animations or interactivity. For example, creating a simple line of code like ellipse(50, 50, 100, 100); draws a circle on the screen with minimal effort. This approach allows creative professionals to focus more on the design and artistic elements of their work rather than struggling with technicalities.
Built-in Libraries
Processing also offers a rich set of libraries that extend its functionality beyond basic visual design. These libraries are designed to support various creative applications, such as working with sound, video, and 3D graphics. Additionally, Processing integrates well with other tools and platforms, such as Arduino, allowing users to develop interactive installations and real-world projects that bridge the digital and physical worlds.
Processing also allows users to create and share their own libraries, which can then be used by others in the community. This collaborative approach has contributed to the platform’s evolution, with thousands of libraries now available for everything from machine learning to data visualization.
The Processing Foundation and Community
In 2012, Reas and Fry, alongside Daniel Shiffman, co-founded the Processing Foundation, a nonprofit organization dedicated to supporting and advancing the Processing project. This initiative provided a more formal structure for the development of Processing, ensuring its sustainability and continued growth. The foundation also works to promote the use of Processing in educational settings, supporting the creation of resources, tutorials, and workshops designed to teach creative coding.
Daniel Shiffman, an influential figure in the Processing community, played a pivotal role in making the language accessible to a broader audience. His tutorials, books, and online presence have significantly contributed to Processing’s popularity, particularly among students and educators. Shiffman’s emphasis on making coding fun and accessible aligns with the core mission of Processing—to engage people in the creative process through programming.
In 2014, Johanna Hedva joined the Processing Foundation as its Director of Advocacy, further strengthening the foundation’s mission of promoting creative coding and supporting diverse, inclusive communities. Hedva’s role was instrumental in expanding the reach of Processing and fostering collaboration among users around the world.
