WasmGPU.createTransform().positionPtr¶

Summary¶

WasmGPU.createTransform().positionPtr returns the WebAssembly memory pointer to this transform's local position vector. The pointer references three contiguous f32 values (x, y, z) in the global transform store. Use this for zero-copy interop when calling WasmGPU memory view APIs or custom WASM routines. Treat pointer-backed memory as advanced API surface and keep lifetime rules in mind.

Syntax¶

WasmGPU.createTransform().positionPtr: WasmPtr
const ptr = transform.positionPtr;

Parameters¶

This API does not take parameters.

Returns¶

WasmPtr - Byte offset into WebAssembly linear memory for local position.

Type Details¶

type WasmPtr = number;

Example¶

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

const t = wgpu.createTransform().setPosition(1, 2, 3);
const ptr = t.positionPtr;
const xyz = wgpu.interop.view(Float32Array, ptr, 3);

console.log(ptr, Array.from(xyz));
