Class HairVisual

Used to simulate and render hairstyles with realistic lighting and physics.

See

Example

//@input Component.HairVisual hair

var width = 1;
var wind = new vec3(5,0,0);

script.hair.onInitialized = InitializeHair;

function InitializeHair(hv){
    //change hair width
    hv.strandWidth = width;
    
    //add wind to hair
    hv.windEnabled = true;
    hv.windForce = wind;
}

Properties

clumpDensity

clumpDensity: number

Density of each clump, higher number would result in "messier" looking hair.

clumpRadius

clumpRadius: number

Offset amount of hair roots.

clumpTipScale

clumpTipScale: number

Offset amount of hair tips.

colliders

colliders: ColliderComponent[]

List of all colliders assigned to the hair simulation of the current hair visual.

collisionEnabled

collisionEnabled: boolean

Determines if collision is enabled for hair.

collisionFriction

collisionFriction: number

Determines amount of friction for collision between hair strands.

collisionOffset

collisionOffset: number

Determines how much position offset collision will cause.

collisionStiffness

collisionStiffness: number

Determines how stiff the collision is.

damp

damp: number

Higher value of damp will cause hair to have less free movement.

density

density: number

Amount of density created to thicken hair.

enabled

enabled: boolean

If disabled, the Component will stop enacting its behavior.

extentsTarget

extentsTarget: ScreenTransform

When a ScreenTransform is present on this SceneObject, and extentsTarget is a child of this SceneObject, extentsTarget will be repositioned to match the exact area this MeshVisual is being rendered. Very useful for Image and Text components.

fallbackModeEnabled

fallbackModeEnabled: boolean

This enables fallback mode which turns off physics simulations; it is recommended to enable fallback mode on lower-end devices. It will be enabled automatically if device doesn't support hair simulation feature.

friction

friction: number

Amount of friction for hair strands.

gravity

gravity: vec3

Gravity force that gets added for hair's physics simulation.

hairMaterial

hairMaterial: Material

Material used by this simulation to render hair.

hairResolution

hairResolution: number

Determines the amount of vertices on each strand. 0 means using original number of the strands. 1 is the smallest resolution for hair. Keep in mind when you change this property, the hair geometry will be regenerated.

horizontalAlignment

horizontalAlignment: HorizontalAlignment

When a ScreenTransform is attached to the same SceneObject, this controls how the mesh will be positioned horizontally depending on stretchMode.

meshShadowMode

meshShadowMode: MeshShadowMode

None = 0, Caster = 1, Receiver = 2

noise

noise: number

Offset of hair density.

onInitialized

onInitialized: (hairVisual: HairVisual) => void

This function gets called when the hair visual is initialized in the Lens.

ReadonlysceneObject

sceneObject: SceneObject

The scene object this component is on.

selfCollisionEnabled

selfCollisionEnabled: boolean

If enabled, hair strands will collide with themselves.

selfCollisionFriction

selfCollisionFriction: number

Friction of collisions between hair strands.

selfCollisionRadius

selfCollisionRadius: number

Radius limit of collisions between hair strands.

selfCollisionStiffness

selfCollisionStiffness: number

Determines how stiff collision between hair strands are.

shadowColor

shadowColor: vec4

Affects the color of shadows being cast by this MeshVisual. The color of the cast shadow is a mix between shadowColor and the material's base texture color. The alpha value of shadowColor controls the mixing of these two colors, with 0 = shadowColor and 1 = shadowColor * textureColor.

shadowDensity

shadowDensity: number

Density of shadows cast by this MeshVisual.

stiffness

stiffness: number

Higher value of stiffness will make hair move less.

strandTaper

strandTaper: number

The taper size of each hair towards the tip.

strandWidth

strandWidth: number

The Width of each hair strand.

stretchMode

stretchMode: StretchMode

When a ScreenTransform is attached to the same SceneObject, this controls how the mesh will be stretched relative to the ScreenTransform's boundaries.

ReadonlyuniqueIdentifier

uniqueIdentifier: string

verticalAlignment

verticalAlignment: VerticalAlignment

When a ScreenTransform is attached to the same SceneObject, this controls how the mesh will be positioned vertically depending on stretchMode.

windEnabled

windEnabled: boolean

If checked will add wind force to hair simulation.

windForce

windForce: vec3

Amount of wind force added to hair simulation.

Methods

addCollider

clearColliders

  • clearColliders(): void

    Removes all hair colliders from the hair simulation.

    Returns void

destroy

getRenderOrder

getSceneObject

getTransform

getTypeName

isHardwareSupported

  • isHardwareSupported(): boolean

    Returns true if hair simulation is supported by the device.

    Returns boolean

isInitialized

  • isInitialized(): boolean

    Returns true if the hair resources are initialized.

    Returns boolean

isOfType

  • isOfType(type: string): boolean

    Returns true if the object matches or derives from the passed in type.

    Parameters

    • type: string

    Returns boolean

isSame

  • isSame(other: ScriptObject): boolean

    Returns true if this object is the same as other. Useful for checking if two references point to the same thing.

removeColliderByIndex

resetSimulation

  • resetSimulation(): void

snap

  • snap(camera: Camera): void

    Projects screen positions from camera's view onto the mesh's UVs. If the MeshVisual's material uses the same texture as the camera input, the MeshVisual will look identical to the part of the screen it covers.

    Parameters

    Returns void
