[page:LightShadow] →

[name]

This is used internally by [page:PointLight PointLights] for calculating shadows.

Code 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 PointLight and turn on shadows for the light
		const light = new THREE.PointLight( 0xffffff, 1, 100 );
		light.position.set( 0, 10, 4 );
		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

		//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 );

Constructor

[name]( )

Creates a new [name]. This is not intended to be called directly - it is called internally by [page:PointLight].

Properties

See the base [page:LightShadow LightShadow] class for common properties.

[property:Boolean isPointLightShadow]

Read-only flag to check if a given object is of type [name].

Methods

See the base [page:LightShadow LightShadow] class for common methods.

[method:undefined updateMatrices]( [param:Light light], [param:number viewportIndex])

Update the matrices for the camera and shadow, used internally by the renderer.

light -- the light for which the shadow is being rendered.
viewportIndex -- calculates the matrix for this viewport
