C++11/C++14 and OpenGL graphics engine
C++ C CMake GLSL Shell JavaScript

Magnum is 2D/3D graphics engine written in C++11/C++14 and modern OpenGL. Its goal is to simplify low-level graphics development and interaction with OpenGL using recent C++11/C++14 features and to abstract away platform-specific issues.

  • 2D is not an ugly stepchild Many engines out there were created as pure 2D or 3D and the alternative is usually just an afterthought, if it is present at all. If you want to do your next project in 2D only, you have to either relearn another engine from scratch or emulate it in 3D, leaving many things overly complicated. Magnum treats 2D equivalently to 3D so you can reuse what you already learned for 3D and even combine 2D and 3D in one project.

  • Forward compatibility If newer technology makes things faster, simpler or more intuitive, it is the way to go. Magnum by default relies on decent C++11 support and modern OpenGL features and if some feature isn't available, it tries to emulate it using older functionality. However, you are not restricted to use the older functionality directly, if you really want to.

  • Intuitive, but not restrictive API Scripting languages are often preferred to C/C++ because they are designed to have less complicated APIs and less boilerplate code. Magnum is designed with intuitivity in mind, but also with speed and static checks that strongly-typed native code offers. It wraps OpenGL into less verbose and more type-safe API, which is easier to use. Usually the most common way is the most simple, but if you need full control, you can have it.

  • Extensible and replaceable components If you want to use different mathematical library for specific purposes, that new windowing toolkit, your own file formats or another physics library, you can. Conversion of math structures between different libraries can be done on top of pre-made skeleton classes, support for file formats is done using plugins and platform support is done by writing simple wrapper class.


Graphics APIs:

  • OpenGL 2.1 through 4.5, core profile functionality and modern extensions
  • OpenGL ES 2.0, 3.0, 3.1 and extensions to match desktop OpenGL functionality
  • WebGL 1.0, 2.0 and extensions to match desktop OpenGL functionality


  • Linux and embedded Linux (natively using GLX/EGL and Xlib or through SDL2 or GLUT toolkit) Build Status
  • Windows natively or using ANGLE (through SDL2 or GLUT toolkit) Build status
  • OS X (through SDL2 toolkit) Build Status
  • Android 2.3 (API Level 9) and higher
  • Windows RT (Store/Phone) using ANGLE (through SDL2 toolkit)
  • Google Chrome (through Native Client, both newlib and glibc toolchains are supported)
  • HTML5/JavaScript (through Emscripten)


  • Actively maintained Doxygen documentation with tutorials and examples. Snapshot is available at
  • Vector and matrix library with implementation of complex numbers, quaternions and their dual counterparts for representing transformations.
  • Classes wrapping OpenGL using RAII principle and simplifying its usage with direct state access and automatic fallback for unavailable features.
  • Extensible scene graph which can be modified for each specific usage.
  • Plugin-based data exchange framework, tools for manipulating meshes, textures and images.
  • Pre-made shaders, primitives and other tools for easy prototyping and debugging.


You can either use packaging scripts, which are stored in package/ subdirectory, or compile and install everything manually. Note that Magnum documentation contains more comprehensive guide for building, packaging and crosscompiling.

Minimal dependencies

  • C++ compiler with good C++11 support. Compilers which are tested to have everything needed are GCC >= 4.7, Clang >= 3.1 and MSVC 2015. On Windows you can also use MinGW-w64. GCC 4.6, 4.5, 4.4 and MSVC 2013 support involves some ugly workarounds and thus is available only in compatibility branch.
  • CMake >= 2.8.9
  • Corrade - Plugin management and utility library. You can get it at

Note that full feature set is available only on GCC 4.8.1 and Clang 3.1.

Compilation, installation

The library (for example with support for SDL2 applications) can be built and installed using these four commands:

mkdir -p build && cd build
cmake .. \
make install

See Doxygen documentation for more information about enabling or disabling additional features and targeting different platforms such as OpenGL ES.

Building and running unit tests

If you want to build also unit tests (which are not built by default), pass -DBUILD_TESTS=ON to CMake. Unit tests use Corrade's TestSuite framework and can be run using

ctest --output-on-failure

in build directory. Everything should pass ;-)

Building documentation

The documentation is written in Doxygen (version 1.8 with Markdown support is used, but older versions should do good job too) and additionally uses Graphviz for class diagrams and TeX for math formulas. The documentation can be build by running:


in root directory (i.e. where Doxyfile is). Resulting HTML documentation will be in build/doc/ directory. You might need to create build/ directory if it doesn't exist yet.


The Doxygen documentation has a thorough guide how to start using Magnum in your project.


The engine itself is kept as small as possible with only little dependencies. Additional functionality, often depending on external libraries, is provided in separate repositories.
