    | Variable Pattern | Type|Description                                                  |
    | ---------------- | ------------------------------------------------------------ | ------------------------------------------------------------ |
    | `name_p`         | `Vector3`                                    |The position value of the `name` object.|
    | `name_s`         | `Vector3` |The scale value of the `name` object.|
    | `name_r`         | `Vector3` |The rotation value of the `name` object, **in degree.**|
    | `name_wp`        | `Vector3` |The world position value of the `name` object.|
    | `name_ws`        | `Vector3` |The world scale value of the `name` object.|
    | `name_wr`        | `Vector3` |The world rotation value of the `name` object.|
    | `name_pp`        | `Vector2` |The position value in screen percentage of the `name` object. Please refer [Here](https://github.com/pofulu/Spark-AR-PFTools/tree/master/PFScreen) for more details.|

Please note that you should avoid using the same base name. For example, these object named `name #`, `name   #`, `# name ` or `#  name ` will cause conflict in Patch variables.
