The game engine was written from scratch in C++ as a mostly independent component, and includes support for features such as Python scripting and OpenAL 3D sound.
Developer's Image Library or DevIL, started by Denton Woods, is a cross-platform image library which aims to provide a common API for different image file formats. It consists of three parts: the main library (IL), the utility library (ILU) and the utility toolkit (ILUT), mirroring the corresponding parts of OpenGL.
Basic4GL is an interpreted, open source version of the BASIC programming language which features support for 3D computer graphics using OpenGL. While being interpreted, it is also able to compile programs on top of the virtual machine to produce standalone executable programs.
SuperTuxKart (STK) is a free and open-source kart racing game, distributed under the terms of the GNU General Public License, version 3. It features mascots of various open-source projects. SuperTuxKart is cross-platform, running on Linux, macOS, Windows, iOS (beta), Android systems and Nintendo Switch (homebrew).
OpenCity is a free and open-source software 3D city-building game started in 2003 by France-based Vietnamese programmer Duong-Khang Nguyen. The game mechanics are similar to Simcity, while the game developers don't strive to make it a direct Simcity clone.
FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical engineering. FreeCAD is free and open-source, under the LGPL-2.0-or-later license, and available for Linux, macOS, and Windows operating systems. Users can extend the functionality of the software using the Python programming language.
Mono is a free and open-source .NET Framework-compatible software framework. Originally by Ximian, it was later acquired by Novell, and is now being led by Xamarin, a subsidiary of Microsoft and the .NET Foundation. Mono can be run on many software systems.
Simple and Fast Multimedia Library (SFML) is a cross-platform software development library designed to provide a simple application programming interface (API) to various multimedia components in computers. It is written in C++ with bindings available for Ada, C, Crystal, D, Euphoria, Go, Java, Julia, .NET, Nim, OCaml, Python, Ruby, and Rust. Experimental mobile ports were made available for Android and iOS with the release of SFML 2.2.
GLFW is a lightweight utility library for use with OpenGL. GLFW stands for Graphics Library Framework. It provides programmers with the ability to create and manage windows and OpenGL contexts, as well as handle joystick, keyboard and mouse input.
MonoGame is a free and open source C# framework used by game developers to make games for multiple platforms and other systems. It is also used to make Windows and Windows Phone games run on other systems. It supports iOS, Android, macOS, tvOS, Linux, PlayStation 4, PlayStation Vita, Xbox One and Nintendo Switch. It implements the Microsoft XNA 4 application programming interface (API). It has been used for several games, including Bastion and Fez.
OpenTK, also known as The Open Toolkit library, is a C# graphics library superseding the Tao Framework. It provides access to graphics tools contained in OpenGL, OpenCL, and OpenAL to a variety of CLR-based languages. Particularly, it is usable with any language utilizing either of the .NET Framework or Mono frameworks for versions prior to 4.0 and .NET Core 3.1 and up, continuing with .NET 5, for major version 4.
