dispose execute? record updateUniforms
alphaMode: PostProcessAlphaMode
clear: boolean

Clear the target before drawing. Set false when several viewport passes share a target.

cornerDetection: boolean

Whether axis-aligned corner-pattern attenuation is enabled. Call updateUniforms() after.

diagonalDetection: boolean

Whether 45-degree patterns are detected. Call updateUniforms() after changing it.

dominantAxisBlend: boolean

Whether blending commits to the stronger axis. Call updateUniforms() after changing it.

edgesTexture: RenderTarget

Intermediate edge and weight targets, exposed for debugging the filter.

engine: EngineContext

Engine captured at task creation.

executionEnabled?: boolean

Runtime frame-graph execution gate, default true. When false, the frame graph keeps the task recorded and its resources alive but skips every pass or built-in execute() call for that frame. This is independent from any task-specific enabled state whose disabled transition may still execute work.

maxSearchSteps: number

How far the pattern search runs along an edge, in pixels. Shallow-angle edges make long runs, so raising this can matter on hard-surface content. Call updateUniforms() after.

minDiagonalRun: number

Shortest diagonal run that counts as a 45-degree pattern. Call updateUniforms() after.

name: string
outputTexture: RenderTarget
scene?: SceneContext

Owning scene for scene-bound tasks. Undefined for scene-less standalone frame graphs.

sourceIsSrgb: boolean

Whether the source texture is an sRGB view. Call updateUniforms() after changing it.

sourceSamplingMode?: PostProcessSamplingMode
sourceTexture: RenderTarget
targetTexture: RenderTarget | null

These four are narrowed to non-optional (as PostProcessTask does) because record() forwards them to the presenting pass every frame, so mutating them genuinely takes effect.

threshold: number

Luma difference that counts as an edge. Call updateUniforms() after changing it.

viewport: NormalizedViewport | null
weightsTexture: RenderTarget

  • Re-upload the pass uniforms. Required after mutating any of threshold, maxSearchSteps, diagonalDetection, minDiagonalRun, cornerDetection, sourceIsSrgb or dominantAxisBlend.

    Returns void
