devoted to game / 3D graphics programming with DirectX / OpenGL using C++. Contains downloadable source code for several small and very specific sample programs that I think will be very helpful to anyone trying to learn both 2D and 3D game programming.
a game programming library for C/C++ developers distributed freely, supporting the following platforms: DOS, Unix (Linux, FreeBSD, Irix, Solaris, Darwin), Windows, QNX, BeOS and MacOS X. It provides many functions for graphics, sounds, player input, etc..
an open-source vertical scroller game programmed in C++,OpenGL and SDL. It's designed to run on all important platforms like Linux, MacOS X, Windows, Solaris. (Cool Graphics)
open source high performance realtime 3D engine written and usable in C++ and also available for .NET languages. It is completely cross-platform, using D3D, OpenGL and its own software renderer.
an open source high peformance 3D graphics toolkit, used by application developers in fields such as visual simulation, games, virtual reality, scientific visualization and modelling.
remake of the famous DOS-game "stunts". This DOS-game, which was released in the early 1990's, can be downloaded on several abandonware sites, e.g. the XTC site . It is a 3D racing game.
designed to make multimedia productions (games, screen-savers, demos..) easier and more intuitive to write. Consequences are a complete abstraction of resources management (fonts, images, 3D meshes, files, zip-archives, sounds..) and rendering operations
portable C++ GUI library designed for games using Allegro, SDL and/or OpenGL, comes with a standard set of widgets and can use several different backends for displaying graphics and grabbing user input
an arcade action puzzle game where the objective is to get rid of all incoming balls by rearranging their order. Currently it includes 12 different levels and two modes of gameplay. The engine allows for easy custom level creation with unlimited number of paths, different speeds, ball-sizes, and rules.
a framework for developing games. Open source extendable, object-oriented game engine written in C++engine with cross-platform plugin-based architecture.
