Camera Tools
Camera tools provide a convenient way to manipulate the camera that generates the view in the viewport. Four tools, Reset Camera, Pick and Roll, Take Snapshot, and Toggle Quick Interaction Mode can be found in the camera tool bar as shown below.

Reset Camera
This tool resets the camera to its original status when the VWS file is first loaded. Effectively, it restores the view to its original position, orientation, and zooming status.
Pick and Roll
While you can rotate the view by pressing the mouse's left button and dragging, the rotation is with respect to a default pivot point. You can customize the pivot point of rotation with this tool by first picking an object in the viewport and then do the rotation as usual. You will notice that the rotation is now about the center of the picked object.
Take Snapshot
This tool captures the screen shot of the viewport area and saves the image to a PNG file.
Toggle Quick Interaction Mode
This tool toggles on and off the quick interaction mode. In the quick interaction mode, geometric modes are only rendered in wireframes and there is no shade or texture rendered when you manipulate the scene of the viewport (translate, zoom in/out, or rotate the view). This mode also hides volume rendering during the manipulation. Only when you finish the manipulation, the view is recovered to whatever the original rendering status – if you have shade, texture, or volume rendering, they will show.
This tool is useful when you have complicated models and want the view to be more responsive.
