poIImagePlane LocateByMultPoints
Transforms the model based on a list of points to align it to a 2D image plane.
Syntax
Imageplane_handle LocateByMultPoints pointList execute
Application
HyperView Tcl Modify
Description
This command aligns the model with an image plane. The model is transformed to match the perspective of an image.
Inputs
- pointList
- String containing at least seven corresponding model and image points that would be used for an alignment
- execute
- Boolean value set to true will calculate alignment and update the view. A false value will calculate alignment but not store or update the view, it is used to update alignment error in order to give users a sense of how good the current alignment points are.
