Obtain the XYZ point coordinates of a point that the user just clicked on.
 Parameters

[out]  x  the x coordinate of the point that got selected by the user 
[out]  y  the y coordinate of the point that got selected by the user 
[out]  z  the z coordinate of the point that got selected by the user

int pcl::visualization::PointPickingEvent::getPointIndex 
( 
 ) 
const 

inline 
Obtain the ID of a point that the user just clicked on.
 Warning
 If the cloud contains NaNs the index returned by this function will not correspond to the original indices. To get the correct index either sanitize the input cloud to remove NaNs or use the PointPickingEvent::getPoint function to get the x,y,z of the picked point and then search the original cloud for the correct index. An example of how to do this can be found in the pp_callback function in visualization/tools/pcd_viewer.cpp

For situations where multiple points are selected in a sequence, return the points indices.
 Parameters

[out]  index_1  index of the first point selected by user 
[out]  index_2  index of the second point selected by user 
 Returns
 true, if two points are available and have been clicked by the user, false otherwise
