3D rotation
Click the 3D rotate button on the toolbar (or press the R key).
Next, press the left mouse button over the image and drag the mouse to rotate the volume around the X and Y axes (parallel to the viewing plane).
By default, the 3D rotate tool is associated with the left mouse button.
On multi-touch devices, touch the image with one finger and drag it to rotate the volume.
Alternatively, Arrows (Up, Down, Left or Right) can be used to perform the 3D rotation.
The orientation cube shown in the upper right corner shows the position of planes facing the viewer.
The rotation angles are presented in the lower right corner.
Roll
Click the Roll button on the toolbar (or press the T key).
Next, press the left mouse button over the image and drag the mouse to rotate the volume around the Z axis (perpendicular to the viewing plane).
Press the Ctrl + Alt keys and drag mouse with the left button down, and the roll tool will be active regardless of the current left mouse button association.
On multi-touch devices, touch the image with two fingers and rotate them to roll the volume.
Alternatively, press the < or > keys.
