Change Display Options for 3D Image Planes

The Display Options sub-tab allows you to control how the media is displayed on the image plane and in the graphics area.

From the 3D Image Plane tab, click the Display Options sub-tab.
Activate the Maintain aspect ratio option to maintain the aspect ratio of the rectangular image plane while the image is being manipulated using the graphical manipulator.
Aspect ratio for 3D image planes is maintained. The base point of the image plane (manipulator) is locked, and the image plane expands or contracts around the base point.
Activate the Stretch option to stretch or fill the screen in the graphics area with the image/video.
Activating this option will deactivate the Maintain aspect ratio option.
Activate the Fit option to resize the image plane to fill its window in the graphics area while reserving the aspect ratio and the entire image plane is within the window.
Activating this option will automatically activate the Maintain aspect ratio and the Stretch options (which cannot be manually deactivated while Fit is selected). Additionally, the manipulators are disabled, since by definition it does not make sense to use the Fit option and at the same time change the image plane size manually.
Activate the Zoom option to zoom the image plane along with the model.

Restriction: Panning of an image plane is currently not available.
Activate the Backface visibility option to always show the backside of image plane regardless of the image plane orientation.
This enables you to show the media on the opposite side of the image plane as the model is being rotated (for example a video shot in left side view will be shown on the backside of the image plane, flipped, when the model view is changed to a right side or other view).
Use the Transparency slider bar to control the transparency of the image plane.
This is particularly useful for applying watermarks onto the graphics area, as well as controlling the visibility of the stacked images.
Use the Cull angle slider bar to adjust the fading of the image plane.
This option provides you with convenient control on the extent of display of the media when the model view is rotated from the view in which the media was captured.

Note: The combination of settings within the Backface visibility, Transparency, and Cull angle options allow you to effectively control the manner in which the media is displayed on the image plane (with model rotations and pan) without obscuring important details.

Restriction: The Stretch and Fit options are not active for 3D image planes.
