GENPO (GENeral Purpose Organ): GENPO is the GENeral Purpose Organ. It replicates the essential features of any pipe, theatre, or reed organ. GENPO reads a description of an organ (a .org XML file) and presents a suitable user interface for operating that organ. There are a number of high quality organ SoundFonts freely available and the .org file maps the stop sounds to organ divisions, manuals and stops. Other facilities such and couplers and presets are available. You may connect one or more MIDI keyboards to GENPO to provide the organ manuals, you can also assign one to be the 'pedalboard'. The program was written as a result of the author trying some other 'virtual organs' and having a hard time either getting them installed, or using them. The philosophy behind the program is to combine a natural interface with full functionality. GENPO does not try hard to look exactly like an organ console - but an organist should feel instantly at home when presented with the console...

The extruded surface is specified with a 2D polyline that is extruded along a 3D path. A local coordinate system allows for additional flexibility in the primitives drawn. Extrusions may be texture mapped in a variety of ways. The GLE library generates 3D triangle coordinates, lighting normal vectors and texture coordinates as output. It uses the GL or OpenGL API's to perform the actual rendering.

GLife: This is a candidate for deletion: Links work but no maintenance since 2000. Looks like a student project. Email to maintainer broken. Poppy-one (talk) 11:36, 31 July 2018 (EDT) Glife is a simulation that uses the concepts found in Artificial Life. Its goal is to provide a limited number of rules, and then watch some sort of "society" emerge. Trends develop as animals interact with the terrain and with each other. This program is an "Artificial Society" program. The rules are placed in the program (and are somewhat customizeable). You then observe what happens; you can also find information on the individual animals or watch specific trends such as "wealth distribution." You place the rules and watch trends and structures emerge. The terrain is a grid, and the circles inside represent the terrain and the animals.

GMT: Generic Mapping Tools is a collection of ~60 GNU/Linux tools that allow users to manipulate (x,y) and (x,y,z) data sets (including filtering, trend fitting, gridding, projecting, etc.) to produce Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots through contour maps to artificially illuminated surfaces and 3-D perspective views in black and white, gray tone, hachure patterns, and 24-bit color. GMT supports 25 common map projections plus linear, log, and power scaling, and comes with support data such as coastlines, rivers, and political boundaries. Since the package is quite large, the authors suggest looking at the list of mirrors on the page to ensure that you download from the one closest to you.
