Rock fragments and gas clouds interacting and collecting more material over time will allow a more realistic planet or moon formation simulation.Ĭross-Platform Support Navigating the home menu in Universe Sandbox with a gamepad.However, due to some limitations of that method, we are now exploring other options more suitable for Universe Sandbox, like Positions Based Fluids (PBF) or Fluid-Implicit-Particle (FLIP). Previously we’ve looked into a method called Smoothed-particle hydrodynamics (SPH) for this simulation.Allowing objects in collisions to deform fluidly will create more realistic collisions, including total disintegration.Collisions: Physically Accurate & Overall More Awesome.This massive undertaking will eventually handle most computations in Universe Sandbox and will improve performance, particularly for physics simulation.As Unity continues to develop their new physics engine based on the Unity Data-Oriented Technology Stack (DOTS) framework, we’ve begun transitioning Universe Sandbox to this new system.This new system will serve as the foundation for spacecraft, thrusters, and megastructures in the future.Anybody up for space-bowling? We’re continuing work to add new physics to allow better human-scale interactions (like bowling pins and satellites).Adding tidal forces to influence water flow in Universe Sandbox is a work in progress.Ĭollision and physics have been and continue to be a significant focus for us this year. Physics, Physics, Physics Tidal forces due to the Moon orbiting close to the Earth dramatically change the Earth’s tides. Revamped star simulation will lay the groundwork for improving stellar evolution.Overhauling our current star simulation code to enable smooth star transitions as their properties change is a large task we’re actively working on.To simultaneously simulate the 691 stars for constellations, we’ve been improving performance for star glows, object labels, and more.This is one of the oldest things on our to-do list. We want you to view and interact with Constellations dynamically.We’re planning to add new star-related features and are working to improve our star simulation. The camera is moving while the stars are stationary. Stellar Simulation The constellation Orion viewed from two different angles in Universe Sandbox. While we would like to do everything listed here this year, new priorities or unanticipated difficulties might arise and delay our plans. Similar-size object collisions now symmetrically heat and fragment both objectsįrom simulation improvements to smoothing out our development process, we’re excited about what’s ahead.Spin planets apart at high rotational speeds with the new Force Spin tool.The Planetscaping tool now includes an eyedropper. Fragments are now longer-lasting, and collisions are more consistent.Consistent Collisions, James Webb, & Planetscaping Tweaks | Update 29.1.This year has already brought one major and one minor update, both focused on our collision-based goals for the year. And what have we already done in 2022? Showcasing some of the updates we’ve already made to Universe Sandbox in 2022. View our “ What’s New” for a chronological list of changes. Collisions are more realistic with updated frictional forces.Manipulate object surfaces with the Planetscaping (Surface Editing) tool.Starlight color on nearby objects updates in real-time.Stars now have Absolute and Apparent Magnitudes, which measure their brightness at different distances.Realistic Object Visibility better reflects what the human eye would see.My Eyes, the Space Goggles Do Nothing | Update 28.1.Object trails project back in time and show their past trajectory.Object collisions now have shockwave-based impacts.Atmosphere Opacity is now simulated (and customization).Cloud speed is now simulated from an object’s temperature and rotational speed.Temperature calculations are smoother at high sim speeds.Snow simulation is more realistic for known and random rocky planets.Oceans fill from lowest to highest elevations (like a bathtub).Splish, Splash, Filling a Bath | Update 26.3.Over the course of 2021, we had 3 major updates and 5 minor updates. Our plans this year include more materials, rigid body collisions, and more! But first, what did we do in 2021? Demonstrating planetscaping, atmosphere opacity, and collision improvements added in 2021. We’re constantly working to make Universe Sandbox even better, and we’ve only scratched the surface.
