WasmGPU.interop.viewOn¶
Summary¶
WasmGPU.interop.viewOn creates a typed-array view on an explicit buffer at a Wasm pointer offset. Use this when you already have the target buffer reference and want typed access.
Syntax¶
WasmGPU.interop.viewOn<T extends WasmTypedArray>(ctor: WasmTypedArrayConstructor<T>, buffer: ArrayBufferLike, ptr: number, len: number): T
const view = wgpu.interop.viewOn(ctor, buffer, ptr, len);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
ctor |
WasmTypedArrayConstructor<T> |
Yes | Typed-array constructor (Float32Array, Uint32Array, Int32Array, Uint8Array, etc.). |
buffer |
ArrayBufferLike |
Yes | Backing buffer to view. |
ptr |
number |
Yes | Byte offset (Wasm pointer) into buffer. |
len |
number |
Yes | Element count for the typed view. |
Returns¶
T - Typed array view on the requested buffer segment.
Type Details¶
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const ptr = wgpu.frameArena.allocF32(8);
const buffer = wgpu.interop.buffer();
const f32 = wgpu.interop.viewOn(Float32Array, buffer, ptr, 8);
f32.set([0, 1, 2, 3, 4, 5, 6, 7]);
