Modeling Dandelion / Evenly Distributing Objects in Spherical Pattern

Okay, so this problem has been driving me nuts all day. I'm attempting to model a dandelion puff, which is, basically, just one seed replicated about a hundred times in a spherical pattern. Now obviously I don't want to model one hundred seeds, so a simple solution would be to create one, and then pattern it in such a way that I create a sort of sphere.  Kind of like this:

Except with dandelion seeds, so I guess it would look like, yanno, a dandelion puff...

I mean, that's the basic idea at least. So how do I pattern an object in a spherical pattern. So far I've achieved this:

Which really isn't much at all, as I have no idea where to go from here as far as even making these lines into simple cylanders, much less actual models of dandelion seeds (plus the process to get here was horrible and not quick to replicate anyway)

 

 

 

 

 

 

 

 

 

Please help! 😞

Thank you!!! Your video was fantastic and incredibly helpful. The method isn't perfect, but it's pretty darn close, and it's both significantly faster and much neater.

Thank you very much

 

Yeah I think it'll be as close as you're gonna get to a "random" spherical pattern. Like I mention in the video, feel free to play with the numbers (nturns, nseeds, prec1 and prec2) to try to get it to look closer to what you want. All these variables form your result so while I was happy with what I ended up with, you may want to play with the numbers to get a different result if you're not. Having the ability to move seeds from the middle to the outside to fill it out more is a pretty powerful thing to be able to do.

 

Anywho. Glad I could help.

Hey guys! I found an exact way to model the dandelion. It came down to a geometry formula for a Pentakis Dodecahedron. Unlike a normal Dodecahedron which has pentagonal tiles like a soccer ball, a Pentakis Dodecahedron has triangular tiles.  Here is a link to the Youtube video for creating the spherical Pentakis Dodecahedron: https://www.youtube.com/watch?v=RFgXOY8WH04

 

I am waiting for validation of the exact formula for the single dimension you enter to control the outside diameter of the sphere. I will share it when I get it validated.

 

Once you get the Pentakis Dodecahedron modeled, you can figure it our from there I'm sure.

Have you, by any chance, validated this yet?
