Class: MotionBlurPost

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:37

Camera motion blur. Each pixel is averaged along the screen-space path it travelled since the previous frame (reconstructed from depth and the previous view-projection), so panning, orbiting and dollying the camera streak the image the way a real shutter does.

Limitation: only camera motion is blurred — objects that move on their own stay sharp, because the G-buffer carries no per-object velocity.

const post = scene.addComponent(PostProcessingComponent);
const blur = post.addPost(MotionBlurPost);
blur.intensity = 0.5;      // 180° shutter

Constructors

Constructor

new MotionBlurPost(): MotionBlurPost

Defined in: src/gfx/renderJob/post/PostBase.ts:35

Returns

MotionBlurPost

Inherited from

PostBase.constructor

Properties

enable

enable: boolean = true

Defined in: src/gfx/renderJob/post/PostBase.ts:23

Inherited from

PostBase.enable

---

isFinalPass

isFinalPass: boolean = false

Defined in: src/gfx/renderJob/post/PostBase.ts:27

When true, PostPass iterates this post AFTER every regular post regardless of attach order — used by TonemapPost so the ACES curve always lands on the fully-composited HDR signal.

Inherited from

PostBase.isFinalPass

Accessors

usesVelocityTexture

Get Signature

get usesVelocityTexture(): boolean

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:47

True when the blur reads MotionVectorPass' per-object velocities.

Returns

boolean

---

intensity

Get Signature

get intensity(): number

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:71

Shutter scale, 0 = off, 0.5 = 180° shutter, 1 = full frame.

Returns

number

Set Signature

set intensity(v): void

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:72

Parameters

v

number

Returns

void

---

samples

Get Signature

get samples(): number

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:75

Samples along the blur vector (2…32).

Returns

number

Set Signature

set samples(v): void

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:76

Parameters

v

number

Returns

void

---

maxBlurPixels

Get Signature

get maxBlurPixels(): number

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:79

Maximum blur length in pixels.

Returns

number

Set Signature

set maxBlurPixels(v): void

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:80

Parameters

v

number

Returns

void

---

frameRateIndependent

Get Signature

get frameRateIndependent(): boolean

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:83

Keep the blur length independent of the frame rate.

Returns

boolean

Set Signature

set frameRateIndependent(v): void

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:84

Parameters

v

boolean

Returns

void

---

prevViewProj

Get Signature

get prevViewProj(): Matrix4

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:97

The view-projection used as "previous" on the last rendered frame.

Returns

Matrix4

---

currViewProj

Get Signature

get currViewProj(): Matrix4

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:99

The view-projection of the last rendered frame.

Returns

Matrix4

Methods

resetHistory()

resetHistory(): void

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:91

Forget the previous camera pose, so the next frame is not blurred. Call after a camera cut / teleport. With per-object velocities this also resets MotionVectorPass, whose texture the blur then reads.

Returns

void

---

onResize()

onResize(): void

Defined in: src/gfx/renderJob/post/MotionBlurPost.ts:165

Returns

void

Overrides

PostBase.onResize

Parameters

view

destroy()

destroy(force?): void

Defined in: src/gfx/renderJob/post/PostBase.ts:143

Parameters

force?

boolean

Returns

void
