 #### Points to note for pseudo-3D rotation
 When performing pseudo-3D rotation on the X and Y axes, the projection is converted to 2D and Z-axis information is lost when the mouse button is released. This means that if you finish dragging while the shape is collapsed, you may not be able to restore it to its original state. In such a case, please use the "undo" function.

+#### Reuse pose image
+Pose image generated by this tool has pose data in the image itself. You can reuse pose information by loading it as the image source instead of a regular image.
