- The default of `mouseButtons.wheel` is:
- `DOLLY` for Perspective camera.
- `ZOOM` for Orthographic camera, and can't set `DOLLY`.
- `ROTATE` is equivalent to `ROTATE_AZIMUTH | ROTATE_POLAR`; use `ROTATE_AZIMUTH` or `ROTATE_POLAR` to restrict rotation to a single axis. The same applies to `TOUCH_ROTATE` / `TOUCH_ROTATE_AZIMUTH` / `TOUCH_ROTATE_POLAR`.
