I am using a jit.world to make a particle system and am following Federico's Amazing Max Stuff tutorial.

Currently, my particles are contained in a cube shape. Can you help me figure out how to contain them within a sphere shape instead?

they are a cube because they are initially placed using random numbers evenly spaced between -1 and 1. 

You could normalise their initial position vector to get a position placed always at 1 unit from the centre. 

Then you could use a random number to randomise it and so get it inside the sphere.

Here's the patch 


And adding [sqrt] in the jit.gen just after [in 1] will generate an even distribution of particles. See
