SpotLightShadow class

This is used internally by SpotLights for calculating shadows.

//Create a WebGLRenderer and turn on shadows in the renderer
final renderer = WebGLRenderer();
renderer.shadowMap.enabled = true;
renderer.shadowMap.type = PCFSoftShadowMap; // default PCFShadowMap

//Create a SpotLight and turn on shadows for the light
final light = 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)
final sphereGeometry = SphereGeometry( 5, 32, 32 );
final sphereMaterial = MeshStandardMaterial( { MaterilaProperty.color: 0xff0000 } );
final sphere = 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)
final planeGeometry = PlaneGeometry( 20, 20, 32, 32 );
final planeMaterial = MeshStandardMaterial( { MaterilaProperty.color: 0x00ff00 } );
final plane = Mesh( planeGeometry, planeMaterial );
plane.receiveShadow = true;
scene.add( plane );

//Create a helper for the shadow camera (optional)
final helper = CameraHelper( light.shadow.camera );
scene.add( helper );

Methods

clone() → LightShadow
Creates a new LightShadow with the same properties as this one.
inherited
copy(LightShadow source) → SpotLightShadow
Copies value of all the properties from the source to this Light.
override
dispose() → void
Frees the GPU-related resources allocated by this instance. Call this method whenever this instance is no longer used in your app.
inherited
getFrameExtents() → Vector2
Used internally by the renderer to extend the shadow map to contain all viewports
inherited
getFrustum() → Frustum
Gets the shadow cameras frustum. Used internally by the renderer to cull objects.
inherited
getViewport(int viewportIndex) → Vector4
inherited
getViewportCount() → int
Used internally by the renderer to get the number of viewports that need to be rendered for this shadow.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toJson() → Map<String, dynamic>
Serialize this LightShadow.
inherited
toString() → String
A string representation of this object.
inherited
updateMatrices(Light light, {int viewportIndex = 0}) → void
Update the matrices for the camera and shadow, used internally by the renderer.
override

Operators

operator ==(Object other) → bool
The equality operator.
