The 3D toolbar allows to:

1. The translation tool: in Figure 1, you can see three arrows which are the handles for GroIMP's 3D translation tool. By dragging the arrows with the mouse, the object is moved along the arrow direction. If you use the middle mouse button for dragging, the movement is in a plane perpendicular to the arrow direction.
2. The rotation tool: It is activated in the toolbar by clicking on the rotation icon. As handles, it displays three circles which can be dragged to rotate the selected object.
3. The scaling tool: It change the scale of an object toward one axis.
