#### Complement COPOPER

Pointcloud Operator dialog box - Complement Operator

This operation hides all data that was shown and brings back all the data that was hidden.

For example, if you had 10,000 data points in a COP command, and it was filtered to 3000 points in a COPOPER command. The COPOPER/COMPLEMENT command would take the 7,000 data points that weren’t used in that referenced COPOPER command.

You can use this with selections. If you select with a box, complement lets you determine whether or not you select the data inside the box or outside the box. If you have an entire cloud of points, the complement of it is an empty set. The complement of an empty set, is the entire cloud of points.

Clicking Create inserts a COPOPER/COMPLEMENT command into the Edit Window like the following example:

COPOPER9 =COPOPER/COMPLEMENT,SIZE=0

REF,COPOPER4,,

The Pointcloud Operator dialog box allows you to select the complement by choosing the "Complement" Operator and clicking Apply.
