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..
the first and only fully integrated 3D graphics creation suite allowing modeling, animation, rendering, post-production, realtime interactive 3D and game creation and playback with cross-platform compatibility - all in one tidy, easily and free.
a library for collision detection of three-dimensional objects undergoing rigid motion and deformation. SOLID is designed to be used in interactive 3D graphics applications
a high-level graphical application framework. Although Agar was initially developed as a game engine for the upcoming Trek to the Cave, it is also being used in different types of applications, such as CAD.
Hardware accelerated 2D full featured middleware for all who want to develop commercial quality 2D games rapidly and easily. It covers all imaginable 2D game genres (DirectX)
a 3D multiplayer online RPG. It is designed to be a purely dynamic, large open environment for players to explore and play out a life however they wish.
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.
With hundreds of published titles, 3D GameStudio authoring suite for 2D, 3D realtime applications. It combines the C-Script programming language with a high-end 3D engine, a 2D engine, a physics engine, a level, terrain and model editor, etc...
