WasmGPU.math.quat.fromAxisAngle

Summary

WasmGPU.math.quat.fromAxisAngle builds a quaternion from an axis and a radian angle. It is the standard bridge from geometric axis-angle to quaternion rotation.

Syntax

WasmGPU.math.quat.fromAxisAngle(axis: number[], angle: number): number[]
const result = wgpu.math.quat.fromAxisAngle(axis, angle);

Parameters

Name Type Required Description
axis number[] Yes Rotation axis [x, y, z]; normalize for predictable results.
angle number Yes Rotation angle in radians.

Returns

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

Type Details

type Quat = number[]; // expected length: 4 ([x, y, z, w])
type Vec3 = number[]; // expected length: 3 ([x, y, z])

Example

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

const axis = [0, 1, 0];
const angle = Math.PI / 4;
const result = wgpu.math.quat.fromAxisAngle(axis, angle);
console.log(result);
