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
.setupRenderTarget( shadow : LightShadow, builder : NodeBuilder ) : Object
Overwrites the default implementation to create a CubeRenderTarget with CubeDepthTexture.
shadow
The light shadow object.
builder
A reference to the current node builder.
Returns: An object containing the shadow map and depth texture.
.setupShadowCoord( builder : NodeBuilder, shadowPosition : Node. ) : Node.
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.
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.
depthTexture
A reference to the shadow map's depth texture.
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.
