Image Plane Graphical Manipulators

The Image Plane graphical manipulators allow you to interactively resize and reposition 2D image planes in the graphics area, and also allow free rotations and translations in a 3-D space for relocating and reorienting 3D image planes. The graphical manipulator is linked to the Image Plane tab, therefore the display of the graphical manipulator is turned off when the tab is closed. To turn on the display of the graphical manipulator for an image plane, right-click on the desired image plane within the Results browser tree structure and select Show Manipulator from the context menu.

2D Manipulator

The 2D manipulator is a rectangular planar area encompassing the image/video selected (with four corner square handles and two centered arrows).

The corner handles be dragged freely on the plane of the area to increase/reduce overall size of area; the two connected sides will follow the dragged corner, while the opposite corner remains stationary. All of the other sides and handles will update accordingly.

Each arrow can be freely dragged along a straight line. The entire rectangular area will be translated accordingly, while its size and shape will remain the same. The square handle can also be dragged on the plane of the area to reposition the rectangular area for any in-plane movements.

Note	The item selected to be dragged (arrow, square handle, or corner handle) will temporarily change color.

3D Manipulator

The 3D manipulator (which is made up of three centered arrows, arc handles, and square handles) allows you to make incremental adjustments to the rotating plane or move the image plane in 3-D space. This manipulator is created based upon the nodes specified using the 2 Point node input collector (N1N2 and IN1IN2) or the 3 Point node input collector (N1N2N3 and IN1IN2IN3).

3D Image Plane Manipulator

Each arrow can be freely dragged along a straight line. The arc handle connecting arrows can also be grabbed to allow rotation of the arrows and the image plane. In addition, the square handles connecting arrows can be freely dragged in space for planar translations to modify the location of the image plane.

Note	The item that is selected to be dragged (arrow, arc handle, or square handle) will temporarily change color.
