DirectionalLightHelper

THREE.DirectionalLightHelper
See theDirectionalLightHelper companion object
class DirectionalLightHelper(var light: DirectionalLight, size: Double, color: Int | String | Color) extends Object3D

Helper object to assist with visualizing a [[DirectionalLight]]'s effect on the scene. This consists of plane and a line representing the light's position and direction.

Attributes

Example 
 val light = new DirectionalLight(0xffffff)
 scene.add(light)
 val helper = new DirectionalLightHelper(light, 5)
 scene.add(helper)
