boolean

true if the linear depth texture is required.

Overrides

AbstractPostEffect.requireLinearDepthTexture

---

requireDepthAttachment()

requireDepthAttachment(): boolean

Defined in: libs/scene/src/posteffect/bloom.ts:87

---

setup()

setup(s): RGHandle

Defined in: libs/scene/src/posteffect/bloom.ts:97

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.

Overrides

AbstractPostEffect.setup

---

apply()

apply(ctx, inputColorTexture, _sceneDepthTexture, _srgbOutput): void

Defined in: libs/scene/src/posteffect/bloom.ts:234

Apply the post effect

Parameters

ctx

DrawContext

inputColorTexture

Texture2D

The previous scene color texture

_sceneDepthTexture

Texture2D

The linear scene depth texture

_srgbOutput

boolean

Whether the result should be gamma corrected

Returns

void

Remarks

The frame buffer of the post effect is already set when apply() is called.

Overrides

AbstractPostEffect.apply

---

needFlip()

needFlip(device): boolean

Defined in: libs/scene/src/posteffect/posteffect.ts:144

Check if the post effect should be rendered upside down.

Parameters

device

AbstractDevice

The device object

Returns

boolean

true if the post effect should be rendered upside down

Inherited from

AbstractPostEffect.needFlip

---

requireMotionVectorTexture()

requireMotionVectorTexture(_ctx): boolean

Defined in: libs/scene/src/posteffect/posteffect.ts:165

Checks whether this post effect requires the motion vector texture

Parameters

_ctx

DrawContext

Returns

boolean

true if the motion vector texture is required.

Inherited from

AbstractPostEffect.requireMotionVectorTexture

---
