WasmGPU.compute.createStorageBuffer¶

Summary¶

WasmGPU.compute.createStorageBuffer allocates a storage-capable GPU buffer wrapper. Use this for read/write compute data, intermediate buffers, and kernel inputs/outputs. By default it is writable from the queue (copyDst: true) but not readable back unless copySrc: true is enabled. The returned StorageBuffer exposes convenience methods like write, read, and readAs.

Syntax¶

WasmGPU.compute.createStorageBuffer(desc: StorageBufferDescriptor): StorageBuffer
const storage = wgpu.compute.createStorageBuffer(desc);

Parameters¶

Name	Type	Required	Description
`desc`	`StorageBufferDescriptor`	Yes	Descriptor that controls initial data, byte length, and usage flags for the storage buffer.

Returns¶

StorageBuffer - Managed storage buffer wrapper with read/write helpers.

Type Details¶

StorageBufferDescriptor¶

type StorageBufferDescriptor = {
    label?: string;
    byteLength?: number;
    data?: BufferSource;
    copyDst?: boolean;
    copySrc?: boolean;
    usage?: GPUBufferUsageFlags;
};

Example¶

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const values = new Float32Array([1, 2, 3, 4, 5, 6, 7, 8]);
const storage = wgpu.compute.createStorageBuffer({
    label: "values",
    data: values,
    copySrc: true,
    copyDst: true
});

console.log(storage.byteLength, storage.canReadback);
