Chapter 454: PointShadowNode

Core Idea

Represents the shadow implementation for point light nodes.

Reference Tables

Constructor

Signature
new PointShadowNode( light : PointLight, shadow : PointLightShadow )

Methods

Method	Description
.getShadowFilterFn( type : number ) : function	Overwrites the default implementation to return point light shadow specific filtering functions.
.renderShadow( frame : NodeFrame )	Overwrites the default implementation with point light specific rendering code.
.setupRenderTarget( shadow : LightShadow, builder : NodeBuilder ) : Object	Overwrites the default implementation to create a CubeRenderTarget with CubeDepthTexture.
.setupShadowCoord( builder : NodeBuilder, shadowPosition : Node.<vec3> ) : Node.<vec3>	Overwrites the default implementation so the unaltered shadow position is used.
.setupShadowFilter( builder : NodeBuilder, inputs : Object ) : Node.<float>	Overwrites the default implementation to only use point light specific shadow filter functions.

Key Takeaways

1. PointShadowNode extends: EventDispatcher → Node → ShadowBaseNode → ShadowNode
2. Key methods: getShadowFilterFn, renderShadow, setupRenderTarget, setupShadowCoord.
