Hello, I have some visual tests to do. how can I get a packing of spheres inside a closed shape. goal is to know how many spheres would fit for further build. Ive looked around but didnt find a solution in the forums. Example 10in x 10in x10in cube. filled with 1in diameter spheres. would it…

This need physics; use blender or other softwares

take a look to Bazil nut effect , maybe you can extrapolate to 3d, this files from the kangaroo examples could be helpful too. balloondemo.gh (28.3 KB) floorcollide.gh (13.1 KB)

Do you even need to produce the spheres for this? If you know the volume of your shape - something which can be done easily enough with GH, and you know the system of units you’re working in, then you can calculate how many unit cells it contains. Multiply this by the number of spheres per unit cel…

I think the question isn’t clearly defined. Do you want to know the exact number of spheres which can fit in some volume or just an approximation? Do you want the absolute maximum number possible, or the maximum number while keeping them all in the cubic-close packed structure? The densest possib…

Thanks for the good feedback. I understand the math better now (thanks Ethan!) I still want to make a 3D GH sphere pack calculator. and doesnt have to be super exact, just a good approximation. i found few topics but not a solution way yet: https://www.grasshopper3d.com/forum/topics/geometry-pa…

I dont know blender, but GH does physics too. [image] Sphere Packing Grasshopper Has anyone been able to transfer 2D circle packing to 3D sphere packing? Surface tension may be more Cotonou? But I’m interested in solid sphere packing where the spheres stay spherical? Cave…

This is an idea using voronoi if there is a way to create spheres inside the cells [12] [sphere]

For a rough approximation you can use the volume fraction approach Ethan gives above. The actual number of spheres would generally be less than predicted by this though, depending on their size relative to the volume, its shape, and how they are physically put in there are these ball-bearings pouri…

If, as Daniel stated, my previous method overstates the number of spheres, here’s a solution which will slightly understate it. Since the CCP packing has four spheres per unit cell, if you divide the cell into eight subcells, each one will contain 1/2 sphere. The ideas is to create a lattice of one …

This idea need a scripting maybe ; create network from points where the distance between points is fixed x or >x and the spheres radius is x/2 [15]

I dont know blender, but GH does physics too.

im just not sure how to change this into a full packed volume with a number count.
