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..
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.
(pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation.
library that constitutes a powerful API for handling operating system specific tasks, such as opening an OpenGL window and reading keyboard, mouse and joystick input.
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
You apply the actions to the particle group at each time step, then read back the particle positions and other attributes into your app, or send them directly to the GPU as a vertex array or as geometry instances.
open source 3D graphics toolkit, used in visual simulation, games, virtual reality, scientific visualization and modelling. Runs on all Windows platforms, OSX, GNU/Linux, IRIX, Solaris, HP-Ux, AIX and FreeBSD operating systems.
