-Introduction

-GEM is the Graphics Environment for Multimedia. It was originally written by -Mark Danks to generate real-time computer graphics, -especially for audio-visual compositions. -Because GEM is a visual programming environment, users do not need any experience -in traditional computer languages. -

GEM is a collection of externals which allow the user to create -OpenGL -graphics within Pd, -a program for real-time audio processing by Miller -Puckette (of Max fame). -

There are many different shapes and objects, including polygonal graphics, -lighting, texture mapping, image processing, and camera motion. All of -this is possible in real-time without any previous programming experience. -Because GEM is an add-on library for Pd, -users can combine audio and graphics, controlling one medium from another. -

GEM is supported in part by a grant from the Intel -Research Council for the The Global Visual -Music project of Vibeke -Sorensen, Miller Puckette -and Rand Steiger. -

An important thing to remember is that GEM is NOT an application.  -It is a library that Pd loads at run-time.  Make sure that you see -the section on using GEM with Pd.  This -manual assumes that you have Pd working correctly and can load up patches -already.  If you do not have that working yet, look at the Pd manual -and the GEM FAQ.  Also, it is assumed that you have a basic understanding -of how to use Pd and the idea behind the data flow model.  In other -words, if I ask you to pass a message with 3 floats into an object, you -would know what I mean. -

The system requirements vary depending on your system and what you are -trying to do.  In general, you should have the most powerful computer -available and the best graphics accelerator on the market.  In reality, -people have been doing some amazing work with a Pentium II and an nVidia -Riva TNT or 3Dfx Voodoo2 card.  -If you are on an SGI, then everything from an O2 up seems to be okay.  -The biggest requirement is that you have some kind of OpenGL graphics accelerator.  -This means that a Matrox Millennium II will not run very quickly. -

The other factor is what you are trying to do.  Pushing real-time -video around requires a fast bus, which really only exists on SGIs.  -Doing thousands of texture mapped polygons is great on a PC...if it is -a constant texture.  There are many issues which mean that there is -no one answer to "Is this system good enough?".  In general, you will -have to try and see. -

GEM is now maintained by IOhannes m zmölnig. -So any bug-reports and donations should go to him instead of Mark... -
