Distribute points inside mesh/volume

One trick I have found that is very useful is the distribute points on faces node works in 3d. that is to say, if you have an array of planes and you are scattering points on those faces, it checks the other faces within the poisson radius. Here I am using a plane and an array modifier to make a stack of slices, then distributing points and instancing spheres: [image] Zero collisions, 4 nodes

i.e. instance a bunch of planes separated by 1/2 the Poisson disk distance, distribute points (like in 1st example), then cull the ones inside the volume (like in 2nd example).

Good luck.
