WasmGPU.createTransform().rotationPtr¶

Summary¶

WasmGPU.createTransform().rotationPtr returns the WebAssembly memory pointer to this transform's local quaternion. The pointer references four contiguous f32 values in [x, y, z, w] order. Use this for zero-copy interop with WASM kernels or custom quaternion math pipelines. This pointer remains valid while the transform is alive and not disposed.

Syntax¶

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

Parameters¶

This API does not take parameters.

Returns¶

WasmPtr - Byte offset into WebAssembly memory for local quaternion values.

Type Details¶

type WasmPtr = number;

Example¶

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

const t = wgpu.createTransform().setRotationFromEuler(0.1, 0.2, 0.3);
const quatView = wgpu.interop.view(Float32Array, t.rotationPtr, 4);

console.log(Array.from(quatView));
