i'm a student and just started working in rhino and grasshopper this
semester to explore circle packing as well. (so there is a lot out
there i don't know). but I did something similar where I offset the
circles I wanted to pack and then set the points of intersection of
the offset circles as the centerpoints for the next circle I wanted to
pack whose radii is equal to the offset amount. (I think it would be
much easier with a tangent-tangent-radius circle in grasshopper...but
this still wouldn't solve the problem of more than 2 tangencies. The
solution i've come up with is on a very small scale, and when i
increase the number of circles whose radii vary, then i'm struggling
maintaning points of tangency beyond 4 circles (they start to overlap
at somepoints...and i don't know how to prevent this). And then i
wanted to explore this pheonomenon 3 dimensionally as well. Is there
any suggestions on sphere packing...I don't know how to generate the
3d close-packing lattices (hexagonal and cubic)...much less looking at
randomized close packing of spheres with changing radii (what i've
been working on with circles). thanks!
