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
The string is in the following format: # of points, model node locator strings, x y image points. This is the same format that is returned from GetAlignmentData when the alignment mode is set to IP_MULT_POINT.
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.

Example

To set the sync model of an image plane with index 1 to a model with the index of 1:

Errors

Returns HW_InvalidHandle is image plane handle is invalid. Returns HW_Error if active model or video stream is not valid. Returns -2 if invalid node IDs are found in pointList.
