poIImagePlane GetAlignmentMode
Gets the mode used to align a 3D image plane with a model.
Syntax
Imageplane_handle GetAlignmentMode
Application
HyperView Tcl Query
Description
An image plane in 3D mode can be aligned with a model to check correlation between a video and the simulation. The alignment can be performed using three points on the video and on the model, or using two points and a principal plane. This command returns the mode that was used to align the image plane. The mode determines what data will get returned when calling the GetAlignmentData command.
This command returns “2POINT” for 2 point alignment, and “3POINT” for 3 point alignment.
