WasmGPU.math.quat.slerp

Summary

WasmGPU.math.quat.slerp performs spherical linear interpolation between two quaternions. It provides constant-angular-velocity interpolation for smooth rotation blending.

Syntax

WasmGPU.math.quat.slerp(q1: number[], q2: number[], t: number): number[]
const result = wgpu.math.quat.slerp(q1, q2, t);

Parameters

Name Type Required Description
q1 number[] Yes First quaternion input as [x, y, z, w].
q2 number[] Yes Second quaternion input as [x, y, z, w].
t number Yes Interpolation factor, typically in the range [0, 1].

Returns

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

Type Details

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

Example

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

const q1 = [0, 0, 0, 1];
const q2 = [0, Math.sin(Math.PI / 4), 0, Math.cos(Math.PI / 4)];
const t = 0.35;
const result = wgpu.math.quat.slerp(q1, q2, t);
console.log(result);
