This tool is accessible via the [[File:CcPointListPicking_small.png]] icon in the main upper toolbar or the 'Tools > Point list picking' menu.<br />
<br />
== Description ==<br />
<br />
This tool lets the user pick several points on a cloud so as to create a 'list' of points.<br />
<br />
[[Image:Cc_point_list_picking.jpg|frame|center|'Point list picking' tool in action]]<br />
<br />
This list can then be exported as:<br />
* a file<br />
* a new cloud<br />
* a polyline (picked points are simply connected)<br />
<br />
It is very useful to create a 'Ground Control Points' (GCP) list for instance.<br />
<br />
== Procedure ==<br />
<br />
One and only one point cloud should be selected in order to launch this tool.<br />
<br />
A dedicated dialog will then appear in the top-right corner.<br />
<br />
At any time the user can pick points on the selected cloud in the 3D view. These points will be automatically added to the list.<br />
<br />
Here are the actions that can be undertaken while the dialog is visible:<br />
* cancel the last picking action ([[Image:SmallReset.png]]<br />
* export the list (see below)<br />
* change the marker size in the 3D view (with the ''marker size'' spinbox)<br />
* change the starting index (with the ''start index'' spinbox - default value: 0)<br />
* validate the list (in which case all picked points will be 'saved' as a list of [[Point_Picking#Labels | labels]] and the list will be restored when calling this tool again)<br />
* cancel the picking process (the current list won't be saved - ''see above'')<br />
* if the cloud has been [[Global_Shift_and_Scale | shifted]], the global coordinates can be displayed/exported instead of the local ones<br />
<br />
<br />
Note: see the equivalent [http://www.cloudcompare.org/doc/qCC/CloudCompare_PointListPicking.pdf PDF documentation] for this tool.<br />

<br />
The list can be exported as:<br />
* an ASCII file with 'x,y,z' per line <br />
* an ASCII file with 'index,x,y,z' per line (''the 'index start' parameter is taken into account'')<br />
* a new cloud<br />
* a polyline (not ''closed'')</div>Daniel
