This is all just the beginning, and we have a lot more planned for the future of the project. For instance, the super novas are quite impressive visually. It is based on real physics, so if you make a mistake while building your universe, disaster is imminent. You can modify a solar system into what you think would work. We can now leverage the latest graphics and shader tech to do things like glowing craters, variable water levels, and all manner of eye candy. Download Latest Version for Windows Play god of the universe 1/14 Universe Sandbox 2 lets you control how the universe works. We even support a large number of integration modes, and the entire system is configurable. As well the base gravity simulation is more stable, accurate, and faster. We now simulate climate on planets, stellar evolution for stars, internal material compositions, water level, material phases, detailed physics of bodies impacting, including cratering, shockwaves, land deformation and surface heating. It has a custom physics engine as well, that allows us to do things like multi-threading and even leverage the power of a GPU if it supports OpenCL. Universe Sandbox ² is completely redone from the ground up in a new game engine (Unity 3D). It was limited quite a bit by the technology it was built on, and it only worked on certain platforms. The original Universe Sandbox is mostly a gravity simulator, written primarily by Dan.
