poIImagePlane GetBackFaceVisibility
Gets the back face visibility setting for the image plane.
Syntax
Imageplane_handle GetBackFaceVisibility
Application
HyperView Tcl Query
Description
When an image plane is in 3D mode, the model and image plane may get rotated so that the camera is looking at the back of the plane. The back face visibility setting determines whether the image plane remains visible when the back face is exposed. This command returns the value of the back face visibility setting.
Example
To create two image planes, and then query one of them for its basic properties and
settings:
