GEM Intro

GEM Intro This tutorial gives information about the library of image, video and 3D graphics objects called GEM (Graphics Environment for Multimedia). The tutorial assumes that the reader has pd and GEM properly installed and configured, and this document attempts to treat all platforms equally. Other sources exist for installing GEM and pd on various operating systems and if you need help try the pd mailing list.

GEM can manipulate, images, video, text, 3D models and objects much the same way pd processes audio and MIDI. The aspects of audio, video and control data can mix and interact in many interesting and unique ways, and the purpose of this doc is to help get you started working with GEM quickly and easily.

GEM follows most of the standards set forth by pd for construction of patches, message passing, data formats and so on. The tutorial does not explain the basics of pd patch building, but does try to point out differences between pd audio/MIDI constructs and the ones in GEM.
