Particle Physics Simulator

Toni Sagristà Sellés
Particle physics sandbox with n-body capabilities where the behaviour of the system is driven by each particle's gravity. Most simulation parameters are adjustable, like the gravity strength, the number of particles, the friction or the collision policy. Some of them can even be operated live during the simulation.
Set your initial conditions and just watch the system evolve or intervene to decide the fate of the particles!

Features:
-Real n-body physics simulation, pure gravitational interactions between particles.
-Create walls particles can't trespass. Watch them bounce off.
-Allow or not physically realistic elastic collisions or mergers between particles.
-Configurable particle colorus.
-Configurable background image/colour.
-Configurable gravity strength.
-Configurable particle mass.
-Configurable particle size.
-Configurable friction.
-Accelerometer support.
-Repulsive forces.
-Shoot particles of different sizes.
-Repulsive particles.
-Static particles.
-Simulation area: screen or big area with panning and zooming.
-Enable or disable the central black hole which exerts a neat attractive force towards the center.
-Enable or disable particle trails (disable to improve performance).
-Modify simulation velocity in real time.
-Particle-Particle and Particle-Mesh simulation methods. Use first for accuracy, use second for performance.
-Display grid densities as background in Particle-Mesh method.

Check out the LIVE WALLPAPER version, it's free and it's also in the market! It will remain with the old version of the app by now.

N-Body Live Wallpaper

Toni Sagristà Sellés
The Live Wallpaper version of the Standalone N-Body Simulator.
Have a real gravitational particle simulation in the background of your phone where particles interact with each other by means of gravity.

Features:
-Real n-body simulation, pure gravitational interactions between particles.
-Allow or not phisically realistic collisions and mergers between particles.
-Set particle and background colors.
-Set gravity strength and particle mass.
-Accelerometer support.
-Shoot particles or create repulsive forces using touchscreen.
-Enable the action to expand beyond your screen limits without losing particles.
-Enable or disable the central black hole which exerts a neat attractive force towards the center.
-Enable or disable particle trails (disable to improve performance).

Take into account we're talking about a real n-body simulation. I recommend keeping the number of particles reasonably low for the live wallpaper version (about 10-20), even though it only executes when the screen is on. Does not drain your battery keeping loops or listeners when sleeping.

Give it a try!
