base-config clj/s

circle-intersects-any? clj/s

(circle-intersects-any? circle all-circles)

(circle-intersects-any? padding circle all-circles)

checks if the given circle intersects with any other given circles

circles-intersect? clj/s

(circles-intersect? circle-1 circle-2)

(circles-intersect? padding {c1 :center r1 :radius} {c2 :center r2 :radius})

given two circles and optionallly padding checks if they intersect

gen-packed-circles clj/s

(gen-packed-circles)

(gen-packed-circles config)

(gen-packed-circles config initial-circles)

returns a list of packed circles, where a circle has a :center as 2d vec and :radius. optinally takes a config map containing :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

optionally also takes intial list of circles where a circle has a :center as 2d vec and :radius

in-bound-circle? clj/s

(in-bound-circle? c1 r1 {c2 :center r2 :radius})

given center as 2d vec, radius and a circle as arguments returns true if the provided circle is in bound where a circle has a :center as 2d vec and :radius. meant to be used for :in-bound?

in-bound-rect? clj/s

(in-bound-rect? x-start y-start x-end y-end {[x y] :center r :radius})

given start and end points of a reactangle and a circle as arguments returns true if the provided circle is in bound where a circle has a :center as 2d vec and :radius. meant to be used for :in-bound?

make-circle clj/s

(make-circle center radius)

given center as 2d vec and radius generate a circle

random-in-circle clj/s

(random-in-circle random [x y] radius)

given a random number generator, center as 2d vec and radius of a circle returns random points inside

random-in-rect clj/s

(random-in-rect random x-start y-start x-end y-end)

given a random number generator (taking min and max arguments), start and end points of a reactangle returns random points inside

random-range clj/s

(random-range start end)

given start and end generates a random number in range
