Space Crash Simulator

SPH Planet Collisions

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Space Crash Simulator is the first mobile app with Smoothed Particle Hydrodynamics (SPH) for planetary collisions. Watch as planets collide and break apart in real time, with a robust simulation running a decent number of particles for a detailed, physics-based simulation.. The simulation lets you jump straight into high-energy collisions or customize initial conditions in Setup Mode. Adjust parameters like particle count, planet velocity, and collision accuracy to create your own collision scenarios. SPH simulations are notoriously resource intensive but settings like particle count, accuracy and timescale can be adjusted to allow even weaker devices to run it.

- Fixed protoplanetary disk textures bug - Added an option to use your own images as planet textures. Scroll through the planet textures and after Pluto you will now find a "Custom" texture. Click on the blue text and you will be able to select your own image. - Fixed a touch control bug in setup - Updated native libraries to support 16 KB memory page size. - Unity security fix
