Simple demonstration of using THREE.js with ClojureScript [from a fork of https://gist.github.com/spacemanaki/1157978], now working with thanks to @seabre

three.cljs

(ns three.demo
  (:require [THREE :as THREE]))

(def camera 
  (THREE/PerspectiveCamera. 
    75 
    (/ 800 600) 
    1 
    10000))

(set! (.-z (.-position camera)) 1000)

(def scene (THREE/Scene.))
(def geometry (THREE/CubeGeometry. 400 400 400))
(def obj (js/Object.))

(set! (.-color obj) 0xff0000)
(set! (.-wireframe obj) true)

(def material (THREE/MeshBasicMaterial. obj))
(def mesh (THREE/Mesh. geometry material))
(def renderer (THREE/CanvasRenderer.))

(.add scene mesh)

(.setSize renderer 800 600)

(.appendChild 
  (.getElementById 
    js/document 
    "main-arena") 
  (.-domElement renderer))

(set! (.-dynamic (.-geometry mesh)) true)

(defn render []
  (set! (.-x (.-rotation mesh)) (+ (.-x (.-rotation mesh)) 0.01))
  (set! (.-y (.-rotation mesh)) (+ (.-y (.-rotation mesh)) 0.02))
  (set! (.-verticesNeedUpdating (.-geometry mesh)) true)
  (set! (.-normalsNeedUpdating (.-geometry mesh)) true)
  (.render renderer scene camera))

(defn animate []
  (.requestAnimationFrame js/window animate)
  (render))

(animate)

A few things.

On

(def camera (THREE.Camera. 75 (/ window/innerWidth
                                 window/innerHeight) 1 10000))

THREE.Camera. should be THREE.PerspectiveCamera.

And anywhere you see window/innerWidth and window/innerHeight should be (.-innerWidth js/window) and (.-innerHeight js/window).

Also, if you're not actually compiling in Three.js with cljsbuild, you should add (def THREE js/THREE) after your namespace declaration, but make sure you're actually loading Three.js before your compiled ClojureScript on your webpage.
