Magnum — *Lightweight and modular C++11/C++14 graphics middleware for games and data visualization*

Looking for an open-source library that gives you graphics abstraction and
platform independence on major desktop, mobile and web platforms? Do you want
it to have all the convenience utilities around yet stay small, powerful and
not give up on flexibility? *Here it is.* And it's free to use, even for
commercial purposes.

Beauty of simplicity
====================

Among Magnum essentials is a UTF-8-aware OS, filesystem and console
abstraction, a feature-packed vector math library and a slim C++11 wrapper of
OpenGL / WebGL family of APIs. Build on top of that or opt-in for more.

[See all core features](http://magnum.graphics/features/)

With batteries included
=======================

Shaders and primitives for fast prototyping, algorithms, debugging and
automatic testing, asset management, integration with popular windowing
toolkits and a UI library. Everything fits together but you still have a
choice.

[List the extra features](http://magnum.graphics/features/extras/)

Screws are not glued in
=======================

There's always more than one way to do things. Enjoy the freedom of choice and
integrate your own asset loader, texture compressor, font format or math
library, if you feel the need. Or use any of the various plugins.

per-platform build status.

BUILDING MAGNUM
===============

You can either use packaging scripts, which are stored in the
[package/](https://github.com/mosra/magnum/tree/master/package) subdirectory,
or compile and install everything manually. A short guide is below, for better
introduction it's advised to read through the
[Getting Started Guide](http://doc.magnum.graphics/magnum/getting-started.html)
in the documentation. Complete building documentation covering all platforms
and feature sets is in the [Downloading and building](http://doc.magnum.graphics/magnum/building.html)
page.

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**.
-   **CMake** >= 2.8.12
-   **Corrade** — Plugin management and utility library. You can get it at
    https://github.com/mosra/corrade.

Compilation, installation
-------------------------

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

```sh
git clone git://github.com/mosra/magnum && cd magnum
mkdir -p build && cd build
cmake .. \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DWITH_SDL2APPLICATION=ON
make -j
make install # sudo may be required
```

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

```sh
ctest --output-on-failure
```

in build directory. Everything should pass ;)

Building documentation
----------------------

The documentation is written using [Doxygen](https://doxygen.org). It can be
build by running

```sh
doxygen
```

in the root directory (i.e. where `Doxyfile` is).  You might need to create the
`build/` directory if it doesn't exist yet. Resulting HTML documentation will
be in the `build/doc/` directory. Snapshot of the documentation is
[also available for online viewing](http://doc.magnum.graphics/).

GETTING STARTED
===============

The best way to get started is to read the thorough
[download, build, install and start using Magnum](http://doc.magnum.graphics/magnum/getting-started.html)
in your project. After that, there are various [tutorials and examples](http://doc.magnum.graphics/magnum/example-index.html)
and a complete [feature guide](http://doc.magnum.graphics/magnum/features.html)
explaining all aspects of the library.

RELATED PROJECTS
================

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

-   **Corrade** — main Magnum dependency, a multiplatform utility library:
    https://github.com/mosra/corrade
-   **Magnum Bootstrap** — bootstrap projects for many use cases, helping you
    get up and running in no time: https://github.com/mosra/magnum-bootstrap
-   **Magnum Plugins** — various importer plugins for image, font, audio and
    3D model formats is at https://github.com/mosra/magnum-plugins-plugins/branch/master)
-   **Magnum Integration** — integration with various external math and
    physics, get it at https://github.com/mosra/magnum-integration
-   **Magnum Examples** — examples of engine usage, varying from simple
    *Hello World*-like example to more advanced applications, such as viewer
    for complex 3D models. See it at https://github.com/mosra/magnum-examples
-   **Magnum Extras** — playground for testing new APIs, specialized stuff
    that doesn't necessarily need to be a part of main Magnum repository or
    mutually exclusive functionality: https://github.com/mosra/magnum-extras
-   **libRocket integration** — integrates Magnum as rendering backend into
    [libRocket](https://github.com/libRocket/libRocket) GUI library:
    https://github.com/miguelmartin75/Magnum-libRocket
-   **Dear IMGUI integration** — integrated Magnum as rendering backend into
    [Dear IMGUI](https://github.com/ocornut/imgui) library:
    https://github.com/denesik/MagnumImguiPort
-   **Magnum Inspector** — Gtk-based inspector window running alongside Magnum
    https://github.com/wivlaro/magnum-inspector
