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.

Example

To create a 3D image plane, perform a 2 point alignment, and then query the image plane for alignment parameters:

Note: This example assumes that LS-Dyna Bumper demo model has been loaded.
