![]() ![]() ![]() This older version of Universe Sandbox looks a little plain, but there's still plenty of educational space exploration to be had here. It's hugely improved in every area - graphics, physics, climate simulation and more - and can be yours for $24.99. Or, if you're really enthusiastic about the idea, you might prefer Universal Sandbox 2. It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. But Universal Sandbox Premium ($9.95) removes that restriction, and allows you to create simulations as well as open them. Today we play in the universe sandbox, I forced the sun to go supernova in slow motion to see how long it took before destroying the solar system. Universe Sandbox is a realistic physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale. (That's an hour of manipulating the simulations - you can browse them in a basic way forever.). You only get one hour of playing around like this in the free version, unfortunately, so use it wisely. ![]() Maybe explode something, and watch how the orbits change. Hint: Add objects by using the Search bar in the simulation. The program has a lengthy list of other simulations to explore, from relatively local (Saturn and its rings, various planets and their moons), to very distant (distant stars or entire galaxies) and historic (Pioneer, Voyager, Ulysses and other spacecraft as they fly past planets).īest of all, you can play around with any of this just to see what happens. Explore the Solar System to your heart’s content. That's good, but you're not restricted to the Solar System. It's easy to zoom in and out, or click and drag to move your viewpoint in 3D space. Open the "Solar System" simulation, for instance, and you'll see an animated view of our solar system showing all the planets, the moons and their actual orbits.Ĭlicking near an interesting celestial body displays details like its velocity, mass, diameter, density and more. The program works well as an educational tool. Get instant access to the alpha and a pre-order of the final Universe Sandbox ²: universesandbox.Universe Sandbox Legacy is a physics-based space simulator with some unusual fun extras. When it’s ready, we’ll be sure to let you know. The rewrite will let us quickly add support for native code using SSE as well as native code running C++AMP on CPU or GPU, plus still OpenCL.įull implementation may take a bit, but we’re very excited to see it up and running in Universe Sandbox ². This demonstration shows the performance on an Intel i7 CPU running the rewritten C# engine on Mono. with a space simulator that merges real-time gravity, climate, collision, and mat. Note that the slight stuttering, primarily at the beginning, is caused by the screen recording. Welcome to Universe Sandbox 2 Create & destroy on an unimaginable scale. 50 000 particles around Saturn would normally have brought this simulation to a halt, but now it runs very smoothly: In addition, it will be running asynchronously, which essentially means that even if physics is bogged down with thousands of calculations, the user interface should still be responsive.Ĭheck out Thomas’s video below for a demonstration of how powerful the new system is. If all goes well, this could mean that the physics-side of Universe Sandbox ² will run much faster than it does now. Simulate the capturing of an object (such as a large asteroid) to enter the orbit of the Earth - gaining a second moon 12. Thomas explains in his video description: “The core NBody physics was rewritten from the ground up to give back some of the raw computation speed, which had been lost under layer upon layer of C# sugar coating.” ![]() That being said, sometimes it’s not worth trying to squeeze out the last drop sometimes it’s better to start fresh. Earth and a supernova in Universe Sandbox. But never assume that Thomas, our numerical physics developer, is done with optimization there’s always more performance that can be squeezed out. Steam will now update Universe Sandbox ² to the preview version. The last few alpha updates of Universe Sandbox ² have each included changes in the physics code to improve performance on a wide range of hardware. Set the dropdown menu to ‘ alpha19preview ‘. ![]()
