Class: EnvironmentDirector

Constructors

Constructor

new EnvironmentDirector(port: EnvironmentPort, options?: EnvironmentDirectorOptions): EnvironmentDirector;

Defined in: environment-director.ts:159

Parameters

Parameter	Type
port	EnvironmentPort
options	EnvironmentDirectorOptions

Returns

EnvironmentDirector

Accessors

applied

Get Signature

get applied(): ResolvedEnvironment;

Defined in: environment-director.ts:222

What the port actually holds - current with passthrough applied.

Returns

ResolvedEnvironment

---

blendMode

Get Signature

get blendMode(): 
  | EnvironmentBlendMode
  | null;

Defined in: environment-director.ts:239

How the host composites, when it told us. null means nobody said - which is not the same as "opaque", and an app that dims the world differently per mode should treat it as "assume the safe one".

Returns

| EnvironmentBlendMode | null

---

current

Get Signature

get current(): ResolvedEnvironment;

Defined in: environment-director.ts:217

What the app asked for. Mid-transition, the interpolated value.

Returns

ResolvedEnvironment

---

estimatedLighting

Get Signature

get estimatedLighting(): EstimatedLighting | null;

Defined in: environment-director.ts:254

The last measurement an adapter reported. null when there is none.

Returns

EstimatedLighting | null

---

lightEstimation

Get Signature

get lightEstimation(): 
  | ResolvedLightEstimation
  | null;

Defined in: environment-director.ts:249

The estimation the app asked for, every default filled in.

Returns

| ResolvedLightEstimation | null

---

occlusion

Get Signature

get occlusion(): OcclusionSpec | null;

Defined in: environment-director.ts:244

What the app asked for. null when occlusion was never turned on.

Returns

OcclusionSpec | null

---

passthrough

Get Signature

get passthrough(): boolean;

Defined in: environment-director.ts:230

Returns

boolean

---

transitioning

Get Signature

get transitioning(): boolean;

Defined in: environment-director.ts:226

Returns

boolean

Methods

apply()

apply(specOrName: string | EnvironmentSpec): void;

Defined in: environment-director.ts:262

Snap to a spec (or preset name). Cancels any transition in flight, so a hard cut always wins over a fade that is still running.

Parameters

Parameter	Type
specOrName	string | EnvironmentSpec

Returns

void

---

define()

define(name: string, spec: EnvironmentSpec): void;

Defined in: environment-director.ts:202

Register (or replace) a named preset.

Parameters

Parameter	Type
name	string
spec	EnvironmentSpec

Returns

void

---

dispose()

dispose(): void;

Defined in: environment-director.ts:408

Drop the transition, the listeners, and the port's resources.

Returns

void

---

finish()

finish(): void;

Defined in: environment-director.ts:311

Jump to the end of an in-flight transition. A no-op when there is none.

Returns

void

---

getSensing()

getSensing(feature: 
  | "occlusion"
  | "lightEstimation"
  | "depthTexture"
  | "planes"
  | "meshes"
  | "anchors"
  | "hitTest"): SensingReport;

Defined in: environment-director.ts:387

The last thing an adapter said about a feature. Never undefined.

Parameters

Parameter	Type
feature	| "occlusion" | "lightEstimation" | "depthTexture" | "planes" | "meshes" | "anchors" | "hitTest"

Returns

SensingReport

---

onChange()

onChange(listener: EnvironmentListener): () => void;

Defined in: environment-director.ts:400

Subscribe to changes. Returns the unsubscribe.

Parameters

Parameter	Type
listener	EnvironmentListener

Returns

() => void

---

onSensing()

onSensing(listener: SensingListener): () => void;

Defined in: environment-director.ts:392

Subscribe to sensing reports. Returns the unsubscribe.

Parameters

Parameter	Type
listener	SensingListener

Returns

() => void

---

preset()

preset(name: string): EnvironmentSpec | undefined;

Defined in: environment-director.ts:207

Look a preset up. undefined when it was never defined.

Parameters

Parameter	Type
name	string

Returns

EnvironmentSpec | undefined

---

presetNames()

presetNames(): readonly string[];

Defined in: environment-director.ts:212

The names currently defined, in insertion order.

Returns

readonly string[]

---

setLightEstimation()

setLightEstimation(estimation: 
  | boolean
  | LightEstimationSpec
  | null): void;

Defined in: environment-director.ts:367

Let the host's measurement of the real room take over the light slots.

true takes the defaults (ambient, key and ibl, no shadows), a spec picks slots, and false or null hands the slots back to whatever the app asked for. Nothing is remembered on the way out because nothing was overwritten on the way in: the estimate is a layer, not an edit.

Parameters

Parameter	Type
estimation	| boolean | LightEstimationSpec | null

Returns

void

---

setOcclusion()

setOcclusion(spec: OcclusionSpec | null): void;

Defined in: environment-director.ts:346

Ask for real-world depth occlusion, or null to stop.

The port hears about it only while passthrough is on, because occluding virtual content with a room nobody can see is just deleting content. The spec is REMEMBERED across passthrough changes, so an app can set it once at startup and let entering and leaving AR do the right thing.

Parameters

Parameter	Type
spec	OcclusionSpec | null

Returns

void

---

setPassthrough()

setPassthrough(active: 
  | boolean
  | EnvironmentBlendMode): void;

Defined in: environment-director.ts:326

Tell the director whether the real world is showing. Push this from whatever already knows - on the Reality Collective stack that is the service framework's capability service - rather than reading a session here: a session is the platform layer's to own, not the environment's.

Parameters

Parameter	Type
active	| boolean | EnvironmentBlendMode

Returns

void

---

transition()

transition(specOrName: string | EnvironmentSpec, options?: TransitionOptions): void;

Defined in: environment-director.ts:274

Ease to a spec (or preset name) over durationMs. A non-positive duration is an apply. Starting a transition while one is running eases from WHERE IT IS NOW, so interrupting a dusk halfway does not jump.

Parameters

Parameter	Type
specOrName	string | EnvironmentSpec
options	TransitionOptions

Returns

void

---

update()

update(deltaMs: number): void;

Defined in: environment-director.ts:302

Advance an in-flight transition, and let a polling port do its poll.

A port that senses is ticked on EVERY call, transition or not: depth arriving is not correlated with a fade being in progress.

Parameters

Parameter	Type
deltaMs	number

Returns

void
