Perlin noise particle system

{{$t('general.by')}}
Daan
van Hasselt
Using Perlin noise to determine speed and direction of particles. Time is the third dimension of the noise() function, so if you keep your mouse at the same point the direction of the particles will always be different. The particles leave a trace, and the result is a bit like ink in water. Click the mouse to create a particle-emitter, release mouse and it stops spitting out particles. All particles have an age, become smaller as they get older and eventually die. Press space to clean up your canvas.
