Pure Data (also known as Pd) is a real-time graphical programming environment for audio and graphics processing. Pd's audio functions are built-in; graphical computations require separate packages such as gem (Graphics Environment for Multimedia) or pd-pdp (Pd Packet).

GLU offers simple interfaces for building mipmaps; checking for the presence of extensions in the OpenGL (or other libraries which follow the same conventions for advertising extensions); drawing piecewise-linear curves, NURBS, quadrics and other primitives (including, but not limited to, teapots); tesselating surfaces; setting up projection matrices and unprojecting screen coordinates to world coordinates.
