Improving smoothness of arrow helper head

Questions
1

The head on my arrow helper looks faceted, can this be improved?

It’s hardcoded. The head part has 5 radial segments: three.js/ArrowHelper.js at 191a1ef699a5d53de2cd645c667e7fee184a18fd · mrdoob/three.js · GitHub

arrowHelper = new THREE.ArrowHelper(direction.normalize(), from, length, 0x000000, 0.01, 0.01);

change last two values according to your need…

4

that’s the length and width, not the number of segments

5

well that’s annoying, is it possible to overwrite them after creation?

6

Also show your code how you are creating arrow helpers

@bmb No, but you can substitute it with another geometry, with greater amount of segments.

@prisoner849 you mean literally just replace it with another cone? e.g. arrowhelper.cone = my new cone with more segments

I mean something like this:

arrowhelper.cone.geometry.dispose();
arrowhelper.cone.geometry = new CylinderGeometry( 0, 0.5, 1, 10, 1 );
arrowhelper.cone.geometry.translate(0, -0.5, 0);

Great nice one! Does the trick. I know the original arrow helper uses cylinder, but I ended up using cone just to make it more logical for me.

Thank you for your help
