Project Description

Project resources

GEM stands for Graphics Environment for Multimedia and is an external (plugin) for the computer-music software Pd.

GEM was originally written by Mark Danks to do realtime openGL-based graphics on SGI and Win32 platforms.

Günter Geiger has ported GEM to LINUX. James Tittle has ported GEM to Apple's OS-X.

GEM is now maintained at the IEM by IOhannes m zmölnig. Future developments will be aimed at Linux, OS-X and Win32 platforms.

GEM is open source software, it is free for any use and can be downloaded from the internet. GEM runs on LINUX, OSX, Win32 and IRIX platforms.

GEM follows the programming paradigm of Pd.
