PointLightHelper

THREE.PointLightHelper
See thePointLightHelper companion object
class PointLightHelper(var light: PointLight, sphereSize: Double, color: Int | String | Color) extends Mesh

Helper object to assist with visualizing a [[PointLight]]'s position in the scene. This consists of a spherical wireframe mesh.

Attributes

Example 
 val light = new PointLight(0xffffff, 1, 100)
 light.position.set(10, 10, 10)
 scene.add(light)
 val helper = new PointLightHelper(light, 1)
 scene.add(helper)
