  21. new THREE.Vector3( 0, 0, 0 ),
  22. new THREE.Vector3( 5, -5, 5 ),
  23. new THREE.Vector3( 10, 0, 10 )

  32. <h2>Constructor</h2>
  33. <h3>[name]( [page:Array points] )</h3>
  34. <div>points – An array of [page:Vector3] points</div>
  35. <h2>Properties</h2>
  36. <div>See the base [page:Curve] class for common properties.</div>
  37. <h3>[property:Array points]</h3>
  38. <div>The array of array of [page:Vector3] points that define the curve.</div>
  39. <h3>[property:Boolean closed]</h3>
  40. <div>The curve will loop back onto itself when this is true. False by default</div>
  41. <h3>[property:String type]</h3>
  42. <div>Possible values are `centripetal` (default), `chordal` and `catmullrom`.</div>
  43. <h3>[property:float tension]</h3>
  44. <div>When [page:.type] is `catmullrom`, defines catmullrom's tension. Defaults is *0.5*.</div>
