Classes

Device

Static class for requesting and managing the GPUAdapter and the GPUDevice instances with specified features and limits when provided. It can clean up GPUBuffer, GPUTexture, and GPUQuerySet resources when no longer required and destroy the current GPUDevice.

Properties

OnLost

static OnLost: ((detail) => unknown) | undefined;

Callback with a GPUDeviceLostInfo argument to call when a GPUDevice is lost. When present, prevents an ERROR.DEVICE_LOST from being thrown.

Methods

CreateQuerySet()

static CreateQuerySet(
   type, 
   count, 
label?): Promise<GPUQuerySet | undefined>;

Create and cache a new GPUQuerySet.

Parameters

Parameter	Type	Description
type	GPUQueryType	The type of queries managed by the GPUQuerySet.
count	number	The number of queries managed by the GPUQuerySet.
label?	string	GPUQuerySet label. Defaults to DescriptorLabel when not provided.

Returns

Promise<GPUQuerySet | undefined>

See

GPUTiming which uses a "timestamp" query set.

Destroy()

static Destroy(
   buffers?, 
   textures?, 
   querySets?): void;

Remove initialized GPUAdapter and GPUDevice instances, reset internal state, and destroy GPUBuffer, GPUTexture, and GPUQuerySet resources if passed as arguments.

Parameters

Parameter	Type	Description
buffers?	GPUBuffer | GPUBuffer[]	Optional buffers to destroy.
textures?	GPUTexture | GPUTexture[]	Optional textures to destroy.
querySets?	GPUQuerySet | GPUQuerySet[]	Optional query sets to destroy.

Returns

void

SetRequiredFeatures()

static SetRequiredFeatures(features): Promise<Set<GPUFeatureName>>;

Set optional features when requesting a GPUDevice. The request will fail if the GPUAdapter cannot provide them. Must be called before initializing the Renderer, Computation, or TextureUtils or the CreateQuerySet method call.

Parameters

Parameter	Type	Description
features	GPUFeatureName | GPUFeatureName[]	List of fearures to request from the adapter.

Returns

Promise<Set<GPUFeatureName>>

Accessors

AdapterOptions

Set Signature

set static AdapterOptions(options): void;

Set optional RequestAdapterOptions when requesting a GPUAdapter. Must be called before requesting a GPUDevice.

See

https://www.w3.org/TR/webgpu/#adapter-selection

Parameters

Parameter	Type	Description
options	RequestAdapterOptions	Standard GPURequestAdapterOptions with an optional forceCompatibility flag to enable compatibility mode even when the target device supports core.

Returns

void

RequiredLimits

Set Signature

set static RequiredLimits(requiredLimits): void;

Set optional device limits when requesting a GPUDevice. The request will fail if the GPUAdapter cannot provide them. Must be called before initializing the Renderer, Computation, or TextureUtils or the CreateQuerySet method call.

Parameters

Parameter	Type	Description
requiredLimits	Record<string, number> | undefined	List of limits to request from the adapter.

Returns

void

DefaultQueue

Set Signature

set static DefaultQueue(descriptor): void;

Set the descriptor for the default GPUQueue.

Parameters

Parameter	Type	Description
descriptor	GPUQueueDescriptor | undefined	Default queue descriptor object.

Returns

void

DescriptorLabel

Set Signature

set static DescriptorLabel(label): void;

Set the descriptor label for the GPUDevice.

Parameters

Parameter	Type	Description
label	string | undefined	Device descriptor label.

Returns

void

PreferredCanvasFormat

Get Signature

get static PreferredCanvasFormat(): GPUTextureFormat;

Get the optimal GPUTextureFormat for the current system.

See

https://www.w3.org/TR/webgpu/#dom-gpu-getpreferredcanvasformat

Returns

GPUTextureFormat

The only possible values are "rgba8unorm" and "bgra8unorm".

VERSION

Get Signature

get static VERSION(): string;

Returns

string

The current version of the library.
