Creates a visual aid consisting of a spherical Mesh for a HemisphereLight.
const light = new v3d.HemisphereLight(0xffffbb, 0x080820, 1); const helper = new v3d.HemisphereLightHelper(light, 5); scene.add(helper);
light — The light being visualized.
size — The size of the mesh used to visualize the light.
color — (optional) if this is not the set the helper will take the color of the light.
See the base Object3D class for common properties.
Reference to the HemisphereLight being visualized.
Reference to the hemisphereLight's matrixWorld.
See Object3D.matrixAutoUpdate. Set to
false here as the helper is using the
The color parameter passed in the constructor. Default is
undefined. If this is changed, the helper's color will update the next time update is called.
See the base Object3D class for common methods.
Frees the GPU-related resources allocated by this instance. Call this method whenever this instance is no longer used in your app.
Updates the helper to match the position and direction of the .light.
