apply(ctx, inputColorTexture, sceneDepthTexture, srgbOutput): void

Defined in: libs/scene/src/posteffect/fxaa.ts:34

Apply the post effect

Parameters

ctx

DrawContext

inputColorTexture

Returns

void

Checks whether this post effect requires the motion vector texture

Parameters

_ctx

setup()

setup(s): RGHandle

Defined in: libs/scene/src/posteffect/posteffect.ts:193

Declare this effect's passes on the render graph.

The default implementation wraps AbstractPostEffect.apply into a single graph pass, so effects only overriding apply() work unchanged. Multi-pass effects override this method to declare each internal step as its own pass, calling PostEffectSetupContext.createOutput inside the final pass.

Parameters

s

PostEffectSetupContext

Build-time setup context.

Returns

RGHandle

The effect's output color handle.

Inherited from

AbstractPostEffect.setup

---

Defined in: libs/scene/src/posteffect/posteffect.ts:269

Parameters

ctx

DrawContext

Draw context

inputColorTexture

Texture2D

Input color texture

srgbOutput

boolean

Whether the result should be gamma corrected

renderStates?

RenderStateSet

Returns

void

Inherited from

AbstractPostEffect.passThrough

---

drawFullscreenQuad()

protected drawFullscreenQuad(renderStateSet?): void

Defined in: libs/scene/src/posteffect/posteffect.ts:288

Draws a fullscreen quad

Parameters

renderStateSet?

RenderStateSet

Render states that will be used when drawing the fullscreen quad.

Returns

void

Inherited from
