EnvironmentVolume class Lighting and environment

A region that overrides the scene look with its settings, contributing by camera position.

A global volume (bounds null) always contributes; a local one contributes fully inside its bounds and fades to nothing across blendDistance outside the surface, scaled by weight. Overlapping volumes apply in priority order (higher last, so it wins). Assign a list to Scene.environmentVolumes over a Scene.baseEnvironment.

Constructors

EnvironmentVolume({required EnvironmentSettings settings, EnvironmentVolumeBounds? bounds, double priority = 0.0, double weight = 1.0, double blendDistance = 0.0})

Properties

blendDistance ↔ double

World-space fade band outside the bounds surface over which the contribution falls from full to zero. 0 is a hard edge.

getter/setter pair

bounds ↔ EnvironmentVolumeBounds?

The region, or null for a global (unbounded) volume.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

priority ↔ double

Blend order; higher priority volumes are applied later (on top).

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

settings ↔ EnvironmentSettings

The look this volume blends toward where it is in effect.

getter/setter pair

weight ↔ double

Master contribution scale, 0..1.

Methods

coverage(Vector3 cameraPosition) → double

This volume's coverage at cameraPosition, 0..1 (before weight).

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.
