Odin is a map generator derived from map generation experiments for a video game called Crypts of Eldor; after requests to release the tool, a decision was made to release a map editor based on this code. Additionally, a Java API is provided so that the map generator can be integrated into new software.
Multithreaded N-Point Gravity Simulation for PC and Android
Create a sun, spin some asteroids around it, and watch them collide and form planets.
An N-Point Gravity Simulator is a realistic simulation in which all points attract each other: even the smallest asteroid has its own gravitational field that can affect even a large sun far away from it.
Can be reused as a library for making games.
