PointShadowNode

Represents the shadow implementation for point light nodes.

Constructor

new PointShadowNode( light : PointLight, shadow : PointLightShadow )

Constructs a new point shadow node.

light | The shadow casting point light.
---|---
shadow | An optional point light shadow. Default is null.

Methods

.getShadowFilterFn( type : number ) : function

Overwrites the default implementation to return point light shadow specific filtering functions.

type | The shadow type.
---|---

Overrides: ShadowNode#getShadowFilterFn

Returns: The filtering function.

.renderShadow( frame : NodeFrame )

Overwrites the default implementation with point light specific rendering code.

frame | A reference to the current node frame.
---|---

Overrides: ShadowNode#renderShadow

.setupShadowCoord( builder : NodeBuilder, shadowPosition : Node.<vec3> ) : Node.<vec3>

Overwrites the default implementation so the unaltered shadow position is used.

builder | A reference to the current node builder.
---|---
shadowPosition | A node representing the shadow position.

Overrides: ShadowNode#setupShadowCoord

Returns: The shadow coordinates.

.setupShadowFilter( builder : NodeBuilder, inputs : Object ) : Node.<float>

Overwrites the default implementation to only use point light specific shadow filter functions.

builder | A reference to the current node builder.
---|---
inputs | A configuration object that defines the shadow filtering. | filterFn | This function defines the filtering type of the shadow map e.g. PCF.
---|---
shadowTexture | A reference to the shadow map's texture.
depthTexture | A reference to the shadow map's texture data.
shadowCoord | Shadow coordinates which are used to sample from the shadow map.
shadow | The light shadow.

Overrides: ShadowNode#setupShadowFilter

Returns: The result node of the shadow filtering.
