Metric Explicit

The Metric Explicit command creates a metric signal explicitly. This allows for the creation of a new signal without input or reference data, unlike other metric commands. Previous versions of Visual3D labeled this command Explicit_Metric.

The pipeline code for this command is as follows, it can be found in the Pipeline Workshop under Metric.

Metric_Explicit
/RESULT_METRIC_NAME=
! /RESULT_METRIC_FOLDER=
/METRIC_VALUE=

The following table shows the command parameters seen above and their descriptions:

The command can be edited in a text editor or in a dialog form. To edit in the dialog pop up form either click on the Edit button in the pipeline workshop or double-click on the pipeline command. The dialog is shown below.

The dialog box allows you to assign values to the command parameters outlined above.

This example will create a metric signal with 3 component values of 1, 2, 3. The resulting signal will be named NEW_SIGNAL and be located in the OFFSET folder.

Metric_Explicit
/RESULT_METRIC_NAME= NEW_SIGNAL
/RESULT_METRIC_FOLDER= OFFSET
/METRIC_VALUE= 1+2+3;

In early implementations of this command the values in Metric_Value were a list of components you wanted the metric explicitly set to (see example above), and expressions were not allowed.

In version 6 Metric_Value can be an expression, but this may lead to some confusion.

For example,

Metric_Explicit
! /RESULT_METRIC_FOLDER=PROCESSED
/RESULT_METRIC_NAME=X
/METRIC_VALUE=1
;

Metric_Explicit
! /RESULT_METRIC_FOLDER=PROCESSED
/RESULT_METRIC_NAME=TEST
/METRIC_VALUE=METRIC::PROCESSED::X+1
;

The processing results for the second command are:

Metric Name : METRIC::PROCESSED::TEST
Metric Expression : VECTOR(METRIC::PROCESSED::X,1)
Metric Value : 1.000000 , 1.000000 ;
The second command be re-written as follows:

Metric_Explicit
! /RESULT_METRIC_FOLDER=PROCESSED
/RESULT_METRIC_NAME=TEST
/METRIC_VALUE=Add(METRIC::PROCESSED::X,1)
;

The processing results for the third command are:

Metric Name : METRIC::PROCESSED::TEST
Metric Expression : Add(METRIC::PROCESSED::X,1)
Metric Value : 2.000000 ;
