An 3D arrow Object.

Example

var dir = new THREE.Vector3( 1, 0, 0 ); var origin = new THREE.Vector3( 0, 0, 0 ); var length = 1; var hex = 0xffff00; var arrowHelper = new THREE.ArrowHelper( dir, origin, length, hex ); scene.add( arrowHelper );

Constructor

ArrowHelper(dir, origin, length, hex, headLength, headWidth )

origin -- Vector3
length -- scalar
hex -- hexadecimal value to define color ex:0xffff00
headLength -- The length of the head of the arrow
headWidth -- The length of the width of the arrow

This creates an arrow starting in origin in the direction dir for a certain length. It is also possible to change color.
