DustSim is a particle simulator leveraging the power of your GPU to allow you to simulate millions of independent particles in realtime. You can manually place attracting masses and spawn particles, or you can simply run any of the preconfigured scenarios.

By default the simulation has only 262 144 particles, but you can increase the number of particles in the settings depending on how powerful your device is.

Well, you shouldnt use SST from now on, cool game btw

This game made me cream

At school, fun to play when bored, 

love the examples that are available, some very satisfying :]

ABSELUTELY AMAZING this is outstanding I love this


The best sim ever man, this game deserves to be on itch.io's front page :D


Mine too. I just love throwing the poles into the dust and destablizing whats suppose to happen

My favorite thing to do

I agree with you Bro-Z. I just like constantly Throwing poles into the Stable Stuff and messing it up

so sasifying

cool!Nice simulator!

if you use tidal waves 2 and put particle influence at max, you will get a cool version of it

tidal wave 2: the sequel: orb.

pls make downloadable game

This game is so cool for meditation.

This would be even more incredible if it supported a VR headset mode!

This is such a cool sim, but I keep running into an issue and I'm not sure if it's intentional. After a little while using it, the particle brush just stops working. The particle count goes up and I can clear them but nothing renders. When I open a preset the particles of that render but brush-painted ones don't.

same I keep having to reload my page to fix it

yeah its annoying

Thanks, this bug should be fixed in the new version(1.03).

very good game

I would also REALLY  love having grid snap

but other than that it is absolutely AWESOME


wow great game

I wish there was a way to stop the simulation :(

There is!

If you go into the simulation options on the second tab you will find a "Speed" setting which controls how fast the simulation is playing. If you set this value to 0% the simulation will be paused.

I'll make a shortcut key for pausing next time I do an update.

thank you!

Can't play the game. Throws up "WEBGL_color_buffer_float is not supported" error when I start it.

It needs WEBGL_color_buffer_float to run. Internet Explorer and possibly Safari doesn't support it and are therefore not compatible.

If you're running either of those you can try switching to another browser.

I think it's also possible that some graphics cards might not support the feature too.

Absolutely mesmerizing. I'd be interested in seeing more options for editing the environment, such as grid snapping for symmetry or a flight path for objects while paused in time.

WOW so this is what god feels like in outer space
