HD (in) Processing

In this paper I describe the new GLGraphics library for the Processing programming language and environment. This library integrates Graphics Processing Unit(GPU)-accelerated effects and textures into the Processing API (Application Program Interface). GLGraphics solves the current limitations of Processing when handling High-Definition video and images in real-time, while maintaining the ease and familiarity of the existing API. This library makes programming with standard shading languages (such as GLSL and Cg) more accessible to the visual artist/designer who uses Processing for creating computer-based artworks. GLGraphics also brings to Processing techniques of GPGPU (General Processing on GPU), which can substantially speed-up simulations of particle systems and other types of complex real-time effects. The usefulness of this library becomes apparent when considering today's intense work in the contexts of interactive installations, augmented reality, data visualization, computer vision, etc., where the need for real-time processing of large amounts of data has become a constant necessity. GLGraphics is undergoing active development at this time, but it already has a significant level of usability and performance. It is an open-source project, released under the GPL. The source code, as well as binary packages, documentation and tutorials can be accessed from this website
