Creates a visual aid consisting of a spherical Mesh for a HemisphereLight.

Code Example


    const light = new v3d.HemisphereLight(0xffffbb, 0x080820, 1);
    const helper = new v3d.HemisphereLightHelper(light, 5);
    scene.add(helper);

Constructor

HemisphereLightHelper(light : HemisphereLight, sphereSize : Float, color : Color | Integer | String)

light — The light being visualized.
size — The size of the mesh used to visualize the light.
