changing arrow head properties of ArrowHelper class Threejs

javascript, three.js

Solution

Good question, but the answer is 'No'. The head of the arrow scales with the arrow's length.

Your only solution is to create your own custom `ArrowHelper`.

three.js r.63

EDIT: This feature has been added to the dev branch three.js r.64dev.

var arrow = new THREE.ArrowHelper( dir, origin, length, hex, headLength, headWidth );

Problem

I'm using the arrow helper class, I found this example http://stemkoski.github.io/Three.js/Helpers.html and I was able to get the arrow working. However my arrowhead is much larger than I would like it to be, I currently have this code ``` var direction = new THREE.Vector3().subVectors(secondVector, firstVector).normalize(); var arrow = new THREE.ArrowHelper(direction, firstVector, computeDistance(node1, node2) - 32, co); bigObject.add(arrow); ``` the arrow starts at firstVector and points to `secondVector is there a way to change the size or any properties of how the arrow head gets drawn (eg stroke weight, arrowhead location, etc.) ? I didn't see anything that looked promising in the documentation. thank you for the help!
