void pcl::visualization::PointPickingEvent::getPoint	(	float &	x,
		float &	y,
		float &	z
	)		const `[inline]`

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

bool pcl::visualization::PointPickingEvent::getPointIndices	(	int &	index_1,
		int &	index_2
	)		const `[inline]`

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
