Rotation

How it works

First initialize quaternion ( you don’t need to know how quaternion work, don’t ask me please🙈)

rotationQuaternion = { x: 0, y: 0, z: 0, w: 0 };

Later set quaternion rotation

setFromAxisAngle(quaternion: Quaternion, axis: { x: number; y: number; z: number }, angle: number): void {

Where axis are rotation axis and angle is angle of rotation

After this always normalize quaternion to prevent errors

normalize(quaternion: Quaternion)

To apply quaternion to game object use applyQuaternion which is built into GameObject functions

applyQuaternion(quaternion: QuaternionUtils.Quaternion)

Example

override Update(): void {
  const rotationSpeed = Math.PI / 2;

  QuaternionUtils.setFromAxisAngle(
    this.rotationQuaternion,
    { x: 0, y: 1, z: 0 },
    rotationSpeed * this.deltaTime
  );
  QuaternionUtils.normalize(this.rotationQuaternion);

  this.cubes.forEach(cube => cube.applyQuaternion(this.rotationQuaternion));
 }
