Member Function Documentation

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

Definition at line 107 of file point_picking_event.h.

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

Obtain the ID of a point that the user just clicked on.

Definition at line 96 of file point_picking_event.h.

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_1index of the first point selected by user
[out]index_2index of the second point selected by user
Returns
true, if two points are available and have been clicked by the user, false otherwise

Definition at line 137 of file point_picking_event.h.

float &  y2,
float &  z2 
) const
inline

For situations when multiple points are selected in a sequence, return the point coordinates.

Parameters
[out]x1the x coordinate of the first point that got selected by the user
[out]y1the y coordinate of the first point that got selected by the user
[out]z1the z coordinate of the firts point that got selected by the user
[out]x2the x coordinate of the second point that got selected by the user
[out]y2the y coordinate of the second point that got selected by the user
[out]z2the z coordinate of the second point that got selected by the user
Returns
true, if two points are available and have been clicked by the user, false otherwise
