Constructor
new AnalyticLightNode( light : Light )
Constructs a new analytic light node.
| light |
The light source. Default is |
Properties
.baseColorNode : Node
This property is used to retain a reference to the original value of AnalyticLightNode#colorNode. The final color node is represented by a different node when using shadows.
Default is null.
.colorNode : Node
The light's color node. Points to colorNode of the light source, if set. Otherwise
it creates a uniform node based on AnalyticLightNode#color.
.isAnalyticLightNode : boolean (readonly)
This flag can be used for type testing.
Default is true.
.shadowColorNode : Node
Represents the light's shadow color.
Default is null.
.shadowNode : ShadowNode
Represents the light's shadow.
Default is null.
.updateType : string
Overwritten since analytic light nodes are updated once per frame.
Default is 'frame'.
- Overrides: LightingNode#updateType
Methods
.disposeShadow()
Frees internal resources related to shadows.
.getLightVector( builder : NodeBuilder ) : Node.<vec3>
Returns a node representing a direction vector which points from the current position in view space to the light's position in view space.
| builder |
The builder object used for setting up the light. |
- Returns: The light vector node.
.setup( builder : NodeBuilder )
Unlike most other nodes, lighting nodes do not return a output node in Node#setup. The main purpose of lighting nodes is to configure the current LightingModel and/or invocate the respective interface methods.
| builder |
The current node builder. |
- Overrides: LightingNode#setup
.setupDirect( builder : NodeBuilder ) : Object | undefined (abstract)
Sets up the direct lighting for the analytic light node.
| builder |
The builder object used for setting up the light. |
- Returns: The direct light data (color and direction).
.setupDirectRectArea( builder : NodeBuilder ) : Object | undefined (abstract)
Sets up the direct rect area lighting for the analytic light node.
| builder |
The builder object used for setting up the light. |
- Returns: The direct rect area light data.
.setupShadow( builder : NodeBuilder )
Setups the shadow for this light. This method is only executed if the light cast shadows and the current build object receives shadows. It incorporates shadows into the lighting computation.
| builder |
The current node builder. |
.setupShadowNode() : ShadowNode
Setups the shadow node for this light. The method exists so concrete light classes can setup different types of shadow nodes.
- Returns: The created shadow node.
.update( frame : NodeFrame )
The update method is used to update light uniforms per frame. Potentially overwritten in concrete light nodes to update light specific uniforms.
| frame |
A reference to the current node frame. |
- Overrides: LightingNode#update
