PointLight class Lighting and environment

A light that radiates from a single world-space point equally in every direction, its influence falling off with distance.

Attach one to the scene by adding a PointLightComponent to a node; the light's world position is the node's world-space translation, so moving the node moves the light. The analytic contribution is layered on top of the image-based-lighting ambient term, the same as DirectionalLight.

Point lights do not cast shadows.

Constructors

PointLight({Vector3? color, double intensity = 1.0, double range = 0.0, double falloffExponent = 2.0})
Creates a PointLight.

Properties

color ↔ Vector3
Linear RGB color of the light.
getter/setter pair
falloffExponent ↔ double
The distance-falloff exponent. 2 (the default) is the physical inverse square; lower values are an artistic control that lets the light reach further without blowing out its near field (a hero light touching distant scenery). Values at or below zero are clamped.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
intensity ↔ double
Scalar multiplier applied to color; the radiance at unit distance.
getter/setter pair
range ↔ double
World-space distance at which the light's influence smoothly reaches zero. 0 means infinite range (pure inverse-square falloff, clamped near the source).
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

noSuchMethod(Invocation invocation) → dynamic
