The BlueMars library does not require any dependancies. However the 2DVisualizer relies on SMFL & SFGUI.

You can build BlueMars on any compiler compliant with C++11 and above. Currently it has been tested on Windows, Linux & OS X with MSVC12 (Visual Studio 2013) and gcc > 4.8.

If you need to compile the 2DVisualizer, you will need to first have SFML & SFGUI

• You can get SFML from source (here) or via your favorite repo manager. (Tested on SMFL 2.1)
• It's better to build SFGUI from source (here)

Once you have downloaded the file you can simply do:

cd <source_dir>
cmake .
make
make install

Be sure that FindSFML.cmake & FindSFGUI.cmake are placed inside the CMake module directory.

BlueMars uses CMake to be platform-independant. You can either use CMake command-line of CMake GUI. 3 flags are availables for compilation:

• BUILD_SHARED_LIBS enables to build as shared lib, disables to build static
• BlueMars_BUILD_2D_VISUALIZER builds the 2D Visualizer (you need SFML & SFGUI)
• BlueMars_BUILD_UNITTEST builds the unittests (gtests dependancy already included)

For example, the following commands will let you build the BlueMars library + the 2D Visualizer

mkdir build && cd build
cmake -DBlueMars_BUILD_2D_VISUALIZER=TRUE ..
make

BlueMars does all the heavy lifting on random generation, caching and chunks continuity to create seemless infite-sized maps.

The core of BlueMars is based on the layer-management system. Each part of your map: altitude, biome, vegetation, animals, civilization can be represented as a layer dependant on some others.

The most simple Layer implemented is the most versatile one: ElevationLayer. It is a Perli Noise-generated layer that you can depend on in your other layers. (For example, you can create a Biome Layer based on 2 "ElevationLayer", one for elevation and one for humidity.

For more examples, feel free to play with the 2D Visualizer.
