Class AutoExposure

WebGPU histogram auto exposure with percentile clipping and submission-aware eye adaptation.

The feature records after HDR post-processing and before the display transform, so Bloom and authored emissive energy share one exposure. It performs no per-frame CPU readback.

Methods

create

create(
context: RenderPipelineCreateContext,
): ForwardRenderPipelineFeatureRuntime
Create independent state for one Renderer. This callback must complete synchronously and must not return a runtime already attached to another Renderer.
Parameters
- context: RenderPipelineCreateContext
Returns ForwardRenderPipelineFeatureRuntime
Implementation of ForwardRenderPipelineFeature.create
- Defined in render/postprocessing/AutoExposure.ts:740

readDiagnostics

readDiagnostics(): Promise<Readonly<AutoExposureDiagnostics>>
Read the latest adapted values when attached to exactly one live renderer.

Returns Promise<Readonly<AutoExposureDiagnostics>>
- Defined in render/postprocessing/AutoExposure.ts:749
