This project is a demonstration of an algorithm to randomly generate islands on a map.
In order to build this software, you will need to install :
- A C++ compiler supporting the C++11 standard such as GCC >= 4.8.
- Qt4, available at qt-project. Qt5 was not tested yet, but it should be compatible.
- OpenGL and GLU libraries.
The demo displays the result in a window. You can navigate through the map using the following commands :
- mouse click and drag : translation on the map
- mouse wheel : zoom in and out
- CTRL + mouse wheel : rotation of the map
Feel free to test several sets of parameters in
To generate islands, the following method was used.
- The map can be seen as a honeycomb where each cell is given a score (initially one). We fill part of these cells with particles at random.
- Whenever we add a particle in a cell, it modifies the scores of the neighboring cells, which is proportional to the probability of the apparition of a new particle. Thus, particles tend to stay close together.
- At the end of this process, we obtain islands made of groups of particles. We convert the scores into a heightmap which is displayed on screen.
This method can be adapted to create a forest (if we see particles as trees), or random ressources on a map.
