Class: TonemapUtil

Defined in: src/util/TonemapUtil.ts:10

CPU reference of the curves in TonemapShader, kept line-for-line in sync with the WGSL. Used to map a mode name to the shader's integer selector, and by tooling / tests that need the expected LDR value for an HDR input (color pickers, LUT bakers, GPU-vs-CPU validation).

Constructors

Constructor

new TonemapUtil(): TonemapUtil

Returns

TonemapUtil

Properties

MODE_INDEX

readonly static MODE_INDEX: Record<TonemapMode, number>

Defined in: src/util/TonemapUtil.ts:12

Shader selector per mode. Order is part of the shader contract.

---

MODES

readonly static MODES: TonemapMode[]

Defined in: src/util/TonemapUtil.ts:22

All mode names, in selector order.

Methods

modeIndex()

static modeIndex(mode): number

Defined in: src/util/TonemapUtil.ts:25

Selector for a mode name; unknown names fall back to ACES (the engine default).

Parameters

mode

string

Returns

number

---

apply()

static apply(mode, rgb, exposure?, whitePoint?): [number, number, number]

Defined in: src/util/TonemapUtil.ts:34

Apply exposure + tone curve to a scene-linear RGB triple.

Parameters

mode

TonemapMode

rgb

[number, number, number]

exposure?

number = 1

whitePoint?

number = 4

Returns

[number, number, number]

linear display-referred RGB (before the sRGB encode)
