Class: IESProfilesPool

Defined in: src/components/lights/IESProfiles.ts:52

Per-Context3D registry of IES profiles. Each engine owns one pool (lazily created through ctx.cache) holding the texture array bound as iesTextureArrayMap plus the profile -> layer assignments, so sibling engines never share GPU textures or the USE_IES_PROFILE shader define. The pool dies with the Context3D cache, so engine teardown / device loss cannot leak a texture from a dead device.

Constructors

Constructor

new IESProfilesPool(ctx): IESProfilesPool

Defined in: src/components/lights/IESProfiles.ts:60

Parameters

ctx

Context3D

Returns

IESProfilesPool

Properties

iesTexture

iesTexture: BitmapTexture2DArray = null

Defined in: src/components/lights/IESProfiles.ts:56

Accessors

use

Get Signature

get use(): boolean

Defined in: src/components/lights/IESProfiles.ts:69

True once any profile is registered — drives the USE_IES_PROFILE shader define.

Returns

boolean

Methods

for()

static for(ctx): IESProfilesPool

Defined in: src/components/lights/IESProfiles.ts:64

Parameters

ctx

Context3D

Returns

IESProfilesPool

register()

register(profile): number

Defined in: src/components/lights/IESProfiles.ts:78

Register a profile and return its texture-array layer index. Idempotent for an already-registered profile. Returns -1 (no IES applied) when the profile has no texture yet or the pool is full.

Parameters

profile

IESProfiles

Returns

number
