Class: LazyFillPrimitive

Experimental

A FillPrimitive whose code loads on first use: the same data, updates and transform, and the same drawing once loaded. Until then it keeps the latest data, transform and viewport size and draws nothing; ready resolves once the fill is drawn (at once when the code has already loaded). A failed load resolves ready too (the fill stays undrawn) and is retried by the next update.

object is the fill's mesh from the start: a hidden placeholder that the fill primitive draws into once loaded, so callers can set its renderOrder (or hold it) at any time.

Constructors

Constructor

Parameters

Parameter	Type
context	PrimitiveContext
data	FillData

Returns

LazyFillPrimitive

object	readonly	Mesh	Experimental Root object to add to a viewport's scene.

Accessors

fill

Get Signature

get fill(): FillPrimitive | null;

Experimental

The underlying fill primitive, once the fill code has loaded (else null).

Returns

FillPrimitive | null

---

ready

Get Signature

get ready(): Promise<void>;

Experimental

Resolves once the fill is drawn: its code has loaded (or failed to) and it holds the data, and so has the code of its pattern paint, if any (plan E8.10).

Returns

Promise<void>

Methods

dispose()

dispose(): void;

Experimental

Release GPU resources. The primitive must not be used afterwards.

Returns

void

Implementation of

Primitive.dispose

---

setTransform()

setTransform(transform): void;

Experimental

Set the data → world transform (cheap: uniforms only, no buffer uploads).

Parameters

Parameter	Type
transform	DataTransform

Returns

void

Implementation of

Primitive.setTransform

---

setViewport()

setViewport(size): void;

Experimental

Update viewport-dependent uniforms (resolution, pixel ratio).

Parameters

Parameter	Type
size	ViewportSize

Returns

void

Implementation of

Primitive.setViewport

---

update()

update(patch): void;

Experimental

Replace or patch the primitive's data. Omitted fields keep their previous values.

Parameters

Parameter	Type
patch	Partial<FillData>

Returns

void

Implementation of

Primitive.update
