WasmGPU.createTransform().rotation¶

Summary¶

WasmGPU.createTransform().rotation returns the local rotation quaternion. Quaternion order is [x, y, z, w] and is normalized by rotation mutator APIs. Use quaternion values for interpolation, rigid-body orientation, and stable 3D rotations without gimbal lock. For user-friendly angle input, use setRotationFromEuler or setRotationFromAxisAngle.

Syntax¶

WasmGPU.createTransform().rotation: number[]
const quaternion = transform.rotation;

Parameters¶

This API does not take parameters.

Returns¶

number[] - Local rotation quaternion as [x, y, z, w].

Type Details¶

type Quaternion = [number, number, number, number];

Example¶

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

const t = wgpu.createTransform().setRotationFromEuler(0, Math.PI / 2, 0);
const [x, y, z, w] = t.rotation;
console.log(x, y, z, w);
