This is how I would write it -
(defrecord Point [x y z])
;;; Only needed in pre Clojure 1.3.0
;;; In Clojure 1.3.0, ->Point will be generated automatically
;; (defn ->Point
;; [x y z]
;; (Point. x y z))
(defn gen-points [n]
(let [random (java.util.Random.)
random-int #(.nextInt random)
random-point #(apply ->Point (repeatedly 3 random-int))]
(repeatedly n random-point)))
Hope this helps.
Regards,
BG
