Adobe Pixel Bender, previously codenamed Hydra, is a programming language created by Adobe Systems for the description of image processing algorithms. The syntax is based on GLSL, and a Pixel Bender program is analogous to an OpenGL fragment shader, and is intended to be a loosely typed version of C++. In addition to its primary purpose of image processing, Pixel Bender can also be used for general mathematical operations which would benefit from the hardware acceleration that it provides. An example of this is audio processing.
