A Clojure (script) library designed for circle packing.
[circle-packing "0.0.0"]
exposes gen-packed-circles
which optionally takes a config map and returns list of circles having :center
as 2d vec and :radius
:min-radius
a number or a 0-arity function returning a number
:max-radius
a number or a 0-arity function returning a number
:radius-step
a number or a 0-arity function returning a number
:max-circles
number
:max-attempts
number
:padding
a number or a 0-arity function returning a number
:random-sampler
a 0-arity function that return a 2d vec of random points
:in-bounds?
a function that takes a circle as argument and return boolean based on bound checks where a circle has a :center
as 2d vec and :radius
{:min-radius 5
:max-radius 10
:max-circles 20
:radius-step 1
:max-attempts 100
:padding 0
:random-sampler #(random-in-rect random-range 0 0 100 100)
:in-bounds? (partial in-bound-rect? 0 0 100 100)}
A few handy utitlies functions are also provided
in-bound-rect?
given start and end points of a reactangle returns true if the provided circle is in bound
in-bound-circle?
given center as 2d vec and radius of circle checks if the provided circle is in bound
random-in-rect
given a random number generator (taking min and max arguments), start and end points of a reactangle returns random points inside
random-in-circle
given a random number generator, center as 2d vec and radius of a circle returns random points inside
Usage with random generator from quil
{:min-radius 5
:max-radius #(q/random 20 30)
:max-circles 100
:padding 4
:random-sampler #(random-in-rect q/random 0 0 150 100)
:in-bounds? (partial in-bound-rect? 0 0 150 100)}
{:min-radius 5
:max-radius #(q/random 20 30)
:max-circles 100
:padding 4
:random-sampler #(random-in-circle q/random [50 50] 50)
:in-bounds? (partial in-bound-circle? [50 50] 50)}
