A Procedural World Generation Library

World is a C++ library and collection of tools used to create a whole, unlimited virtual world using only procedural generation techniques. With a given configuration, the library can generate a large amount of assets (meshes, textures, shaders...) and integrate them all together in a single scene. Then, you can render it with your favorite tool- even in real time!

Please check the World Intro if you want to know more about the library.

Features

• Procedural Content Generation including terrains, trees, grass, rocks...
• Real-time generation, enabling unlimited free exploration
• Automatic level of details management
• A flexible C++ API to craft exactly the world that you want.

The repository also includes:

• VkWorld: Module that uses Vulkan to generate textures using shaders
• World3D: Real-time demo using Irrlicht engine
• Peace: World package for Unity. Embeds a real-time demo too (this is where the screenshot comes from)

There are also a bunch of embryonic packages that are not worth mentioning yet, but might be developped further (Pyworld, blender integration, WorldGUI)

Install

As a library

You can download an archive containing the version of the library that is suited to your operating system here. World was compiled for Linux 64 bit and Windows 64 bit. If you are on Windows and you do not use MSVC, you may consider building the library from sources.

The archive contains the required binary files and headers to run World along your project. If you only use World, no dependency is required. Vkworld requires Vulkan to be installed. On Linux with an Intel CPU, you can install Vulkan easily with your favorite package manager:

sudo apt install libvulkan1 mesa-vulkan-drivers vulkan-utils

If you can not do that please visit the official page and follow the instructions there. These are really good instructions, I guess.

As a Unity Plugin

You can download Peace (World Plugin for Unity) here.

See more about the plugin in the documentation.

Try the demo

You can download a demo of World here. Pick the version that corresponds to you system. After downloading, unzip the archive and run WorldDemo.exe.

Controls are:

• Arrows to move
• Mouse wheel to change speed
• Esc to pause and display overlay with information
• Alt-f4 to quit

From source

See #Build section below.

Build

The World project is built using CMake. All the required dependency to build the core library are included in the repository. Clone it somewhere on your computer, then run the following commands, where WORLD_SOURCE_DIRECTORY is the path to the cloned repository.

mkdir build
cd build
cmake [WORLD_SOURCE_DIRECTORY]

If you are using GCC

Run:

make

If you are using Visual Studio

Open the generated .sln file containing the solution for the whole project. Then, click on Build > Build Solution and it will compile all the binaries.

Dependencies

By default, every existing projects in the repository will be built if their required dependencies are installed. When you run cmake, it tries to find the dependencies, and display a message indicating whether it found the dependency or not. If World does not find the dependency for some reason, you can hint cmake with the path where you have it installed:

cmake -DCMAKE_PREFIX_PATH="[PATH_TO_DEPENDENCY_1];[PATH_TO_DEPENDENCY_2]" [... other arguments]

Here is a table of the dependencies for each project:

Project	Required dependencies
World3D	Irrlicht
VkWorld	Vulkan
World3D with Vulkan support	Irrlicht, Vulkan
Peace native libraries	No dependency
Peace native libraries with Vulkan support	Vulkan

To install them, you can go on these sites:

• Vulkan
• Irrlicht
