Class SpotLightShadow

Example

//Create a WebGLRenderer and turn on shadows in the renderer
const renderer = new THREE.WebGLRenderer();
renderer.shadowMap.enabled = true;
renderer.shadowMap.type = THREE.PCFSoftShadowMap; // default THREE.PCFShadowMap
//Create a SpotLight and turn on shadows for the light
const light = new THREE.SpotLight(0xffffff);
light.castShadow = true; // default false
scene.add(light);
//Set up shadow properties for the light
light.shadow.mapSize.width = 512; // default
light.shadow.mapSize.height = 512; // default
light.shadow.camera.near = 0.5; // default
light.shadow.camera.far = 500; // default
light.shadow.focus = 1; // default
//Create a sphere that cast shadows (but does not receive them)
const sphereGeometry = new THREE.SphereGeometry(5, 32, 32);
const sphereMaterial = new THREE.MeshStandardMaterial({
    color: 0xff0000
});
const sphere = new THREE.Mesh(sphereGeometry, sphereMaterial);
sphere.castShadow = true; //default is false
sphere.receiveShadow = false; //default
scene.add(sphere);
//Create a plane that receives shadows (but does not cast them)
const planeGeometry = new THREE.PlaneGeometry(20, 20, 32, 32);
const planeMaterial = new THREE.MeshStandardMaterial({
    color: 0x00ff00
})
const plane = new THREE.Mesh(planeGeometry, planeMaterial);
plane.receiveShadow = true;
scene.add(plane);
//Create a helper for the shadow camera (optional)
const helper = new THREE.CameraHelper(light.shadow.camera);
scene.add(helper);
