There are three ways I can come up with:

• Use animation clip. You can refer to the animation example we have in the three-vrm repository.
  • Working example: https://pixiv.github.io/three-vrm/packages/three-vrm/examples/animations.html
  • Source code: https://github.com/pixiv/three-vrm/blob/dev/packages/three-vrm/examples/animations.html
• Use an animation library like Tween.js
• Implement an animation logic using math
