SpotLightNode

Module for representing spot lights as nodes.

Constructor

new SpotLightNode( light : SpotLight )

Constructs a new spot light node.

light

The spot light source.

Default is null.

Properties

.colorNode : UniformNode.

Uniform node representing the light color.

Overrides: AnalyticLightNode#colorNode

.coneCosNode : UniformNode.

Uniform node representing the cone cosine.

.cutoffDistanceNode : UniformNode.

Uniform node representing the cutoff distance.

.decayExponentNode : UniformNode.

Uniform node representing the decay exponent.

.penumbraCosNode : UniformNode.

Uniform node representing the penumbra cosine.

Methods

.getSpotAttenuation( builder : NodeBuilder, angleCosine : Node. ) : Node.

Computes the spot attenuation for the given angle.

builder

The node builder.

angleCosine

The angle to compute the spot attenuation for.

Returns: The spot attenuation.

.update( frame : NodeFrame )

Overwritten to updated spot light specific uniforms.

frame

A reference to the current node frame.

Overrides: AnalyticLightNode#update
