ManiWheel is a GL hack for xscreensaver. It draws the spinning Tibetan mantra, "OM MANI PEME HUNG" for the blessing of all beings. It features transparent and no-transparent modes, two internal textures, the option to enable or disable a specular image. The height, radius, shininess, distance, and speed of rotation may be changed. It can also be used to draw any texture in the .rgb format.
QuesoGLC is a free implementation of the OpenGL Character Renderer. The OpenGL Character Renderer (GLC) is a state machine that provides OpenGL programs with character rendering services including scale and rotate text and draw text using lines, filled triangles, or bitmaps. QuesoGLC is based on the FreeType library, provides Unicode support, and is designed to be easily ported to any platform that supports both FreeType and the OpenGL API.
Fandango is a GL-rendered, Python-scripted CAD program. The low-level functionality is programmed in C++, and then the relevant functions are exposed to Python and used as building blocks for more functions. Currently the memory core allows lines, triangles, line strips, and triangle strips. Texture, blending, and lighting can be switched on and off from a command line.
Raydium is a game engine. It provides a set of functions which allows quick and flexible game creation. It features 3D captures, data repositories, in-game live video capture and playback, a themable GUI, networked physics, full Python bindings, and many other things. The main idea is to keep all this as simple as possible.
Aviascene is a virtual environment for remote exploration. Users can download actual earth topography and surface data from USGS, then go exploring. If they get lost, they can launch an aircraft to reconnoiter. It features a high- performance adaptive OpenGL terrain renderer, airplane and wheeled vehicle physics models, and the ability to mark waypoints at GPS coordinates. It can be used to plan a backpacking trip or just as a flight simulator.
