When off, the user can set the Explosion Energy and Fragment Speed.When on, Universe Sandbox will automatically calculate how much energy is released in the explosion and the speed of the fragments, based on the mass and escape velocity of the object.If the Detonation Delay is larger than zero, the explosion will occur after that amount of time has passed within the simulation. If this is set to zero, an object will explode instantly when clicked with the Explode Tool. The Explode button in located in the Tools menu in the bottom bar. If the selected object is a star, the Explode Tool will cause a supernova instead. If this wavefront collides with another object in the simulation, the friction of the exploded material passing the object may trigger friction fragmentation. The explosion also produced a spherical wavefront that expands outwards with time. Get instant access to the alpha and a pre-order of the final Universe Sandbox ²: universesandbox.The Explode Tool will destroy a selected object, removing it from the simulation and producing fragments. set the explosion speed to 100 (though it also happened with the initial which was either speed of 1.00 or 10.00). start new sim and place the sun, pause the sim 2. Rated Overwhelmingly Positive from over 11,000 Steam reviews. Create, destroy, and interact on a scale youve never before imagined. It merges gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. When it’s ready, we’ll be sure to let you know. I came on this one by accident actually since I had accidentially exploded the sun twice when I meant to select the second time. Universe Sandbox is a physics-based space simulator. 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. Note that the slight stuttering, primarily at the beginning, is caused by the screen recording. 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. A Galaxy object is made up of several Galaxy Nebula objects and a single Black Hole (see Galaxy Structure). 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.” A Black Hole in Universe Sandbox is a simulated object representing an actual black hole, or a new black hole created by the user. with a space simulator that merges real-time gravity, climate, collision, and. That being said, sometimes it’s not worth trying to squeeze out the last drop sometimes it’s better to start fresh. Welcome to Universe Sandbox 2 Create & destroy on an unimaginable scale. But never assume that Thomas, our numerical physics developer, is done with optimization there’s always more performance that can be squeezed out. You can alter the speed of time and observe any celestial phenomena you please. You can travel from star to star, from galaxy to galaxy, landing on any planet, moon, or asteroid with the ability to explore its alien landscape. 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. SpaceEngine is a realistic virtual Universe you can explore on your computer.
