Properties
.global : boolean
LightsNode sets this property to true by default.
Default is true.
- Overrides: Node#global
.hasLights : boolean
Whether the scene has lights or not.
.outgoingLightNode : Node.<vec3>
A node representing the outgoing light.
.totalDiffuseNode : Node.<vec3>
A node representing the total diffuse light.
.totalSpecularNode : Node.<vec3>
A node representing the total specular light.
Methods
.customCacheKey() : number
Overwrites the default Node#customCacheKey implementation by including light data into the cache key.
- Overrides: Node#customCacheKey
- Returns: The custom cache key.
.getHash( builder : NodeBuilder ) : string
Computes a hash value for identifying the current light nodes setup.
| builder |
A reference to the current node builder. |
- Overrides: Node#getHash
- Returns: The computed hash.
.getLights() : Array.<Light>
Returns an array of the scene's lights.
- Returns: The scene's lights.
.setLights( lights : Array.<Light> ) : LightsNode
Configures this node with an array of lights.
| lights |
An array of lights. |
- Returns: A reference to this node.
.setup( builder : NodeBuilder ) : Node.<vec3>
The implementation makes sure that for each light in the scene there is a corresponding light node. By building the light nodes and evaluating the lighting model the outgoing light is computed.
| builder |
A reference to the current node builder. |
- Overrides: Node#setup
- Returns: A node representing the outgoing light.
.setupDirectLight( builder : Object, lightNode : Object, lightData : Object )
Sets up a direct light in the lighting model.
| builder |
The builder object containing the context and stack. |
| lightNode |
The light node. |
| lightData |
The light object containing color and direction properties. |
.setupLights( builder : NodeBuilder, lightNodes : Array.<LightingNode> )
Setups the internal lights by building all respective light nodes.
| builder |
A reference to the current node builder. |
| lightNodes |
An array of lighting nodes. |
.setupLightsNode( builder : NodeBuilder )
Creates lighting nodes for each scene light. This makes it possible to further process lights in the node system.
| builder |
A reference to the current node builder. |
