Class: MotionBlurUtil

Defined in: src/util/MotionBlurUtil.ts:8

CPU mirror of the velocity math in MotionBlur_cs, for tooling and tests.

Constructors

Constructor

new MotionBlurUtil(): MotionBlurUtil

Returns

MotionBlurUtil

Methods

projectToUV()

static projectToUV(worldPos, viewProj): [number, number]

Defined in: src/util/MotionBlurUtil.ts:13

Project a world position to screen UV (0..1, origin top-left) with a column-major view-projection matrix. Returns null behind the camera.

Parameters

worldPos

Vector3

viewProj

Matrix4

Returns

[number, number]

velocityPixels()

static velocityPixels(worldPos, currViewProj, prevViewProj, width, height, scale?, maxBlurPixels?): [number, number]

Defined in: src/util/MotionBlurUtil.ts:28

Blur vector in pixels for a world-space point: how far it moved on screen between the previous and the current view-projection, times scale, clamped to maxBlurPixels.

Parameters

worldPos

Vector3

currViewProj

Matrix4

prevViewProj

Matrix4

width

number

height

number

scale?

number = 1

maxBlurPixels?

number = Infinity

Returns

[number, number]

shutterScale()

static shutterScale(intensity, deltaMs, frameRateIndependent): number

Defined in: src/util/MotionBlurUtil.ts:39

Shutter scale actually sent to the shader for a given frame time.

Parameters

intensity

number

deltaMs

number

frameRateIndependent

boolean

Returns

number
