g3n is an OpenGL 3D Game Engine written in Go. It can be used to write cross-platform Go applications that show rich and dynamic 3D representations - not just games! A basic integrated GUI framework is provided, and 3D spatial audio is supported through OpenAL. You can evaluate most of the features by installing and executing G3ND - the G3N demo.
Go 1.8+ is required. The engine also requires the system to have an OpenGL driver and a GCC-compatible C compiler.
On Unix-based systems the engine depends on some C libraries that can be installed using the appropriate distribution package manager.
$ sudo apt-get install xorg-dev libgl1-mesa-dev libopenal1 libopenal-dev libvorbis0a libvorbis-dev libvorbisfile3
$ sudo dnf -y install xorg-x11-proto-devel mesa-libGL mesa-libGL-devel openal-soft openal-soft-devel libvorbis libvorbis-devel glfw-devel libXi-devel
Enable the EPEL repository:
$ sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Then install the same packages as for Fedora - remember to use yum instead of dnf for the package installation command.
The necessary audio libraries sources and DLLs are supplied but they need to be installed manually. Please see Audio libraries for Windows for details. We tested the Windows build using the mingw-w64 toolchain (you can download this file in particular).
Install the development files of OpenAL and Vorbis using Homebrew:
brew install libvorbis openal-soft
The complete engine API reference can be found here: 
There is also the beginning of a Getting Started Guide, and a newly created list of Guides and Tutorials:
Along with those, a good way to learn how to use the engine is to see the source code of the demos from G3ND.
We intend in the future to write/update/complete the following topics to build a user guide:
