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})

Creates a PointLight.

Properties

color ↔ Vector3

Linear RGB color of the light.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

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 setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
