Constructor & Destructor Documentation

PointCloud2Modifier()

sensor_msgs::PointCloud2Modifier::PointCloud2Modifier ( PointCloud2 &  cloud_msg )

inline

Default constructor.

Parameters

cloud_msg

The sensor_msgs::PointCloud2 to modify

Definition at line 102 of file impl/point_cloud2_iterator.h.

Member Function Documentation

clear()

void sensor_msgs::PointCloud2Modifier::clear ( )

inline

remove all T's from the original sensor_msgs::PointCloud2

Definition at line 134 of file impl/point_cloud2_iterator.h.

reserve()

void sensor_msgs::PointCloud2Modifier::reserve ( size_t  size )

inline

Parameters

size	The number of T's to reserve in the original sensor_msgs::PointCloud2 for

Definition at line 111 of file impl/point_cloud2_iterator.h.

resize()

void sensor_msgs::PointCloud2Modifier::resize ( size_t  size )

inline

Parameters

size	The number of T's to change the size of the original sensor_msgs::PointCloud2 by

Definition at line 116 of file impl/point_cloud2_iterator.h.

setPointCloud2Fields()

void sensor_msgs::PointCloud2Modifier::setPointCloud2Fields ( int  n_fields,   ...  )

inline

Function setting some fields in a PointCloud and adjusting the internals of the PointCloud2.

Parameters

n_fields

the number of fields to add. The fields are given as triplets: name of the field as char*, number of elements in the field, the datatype of the elements in the field

E.g, you create your PointCloud2 message with XYZ/RGB as follows:

  setPointCloud2Fields(cloud_msg, 4, "x", 1, sensor_msgs::PointField::FLOAT32,
                                             "y", 1, sensor_msgs::PointField::FLOAT32,
                                             "z", 1, sensor_msgs::PointField::FLOAT32,
                                             "rgb", 1, sensor_msgs::PointField::FLOAT32);

WARNING: THIS DOES NOT TAKE INTO ACCOUNT ANY PADDING AS DONE UNTIL HYDRO For simple usual cases, the overloaded setPointCloud2FieldsByString is what you want.

Parameters

n_fields

the number of fields to add. The fields are given as triplets: name of the field as char*, number of elements in the field, the datatype of the elements in the field

E.g, you create your PointCloud2 message with XYZ/RGB as follows:

  setPointCloud2FieldsByString(cloud_msg, 4, "x", 1, sensor_msgs::PointField::FLOAT32,
                                             "y", 1, sensor_msgs::PointField::FLOAT32,
                                             "z", 1, sensor_msgs::PointField::FLOAT32,
                                             "rgb", 1, sensor_msgs::PointField::FLOAT32);

setPointCloud2FieldsByString()

void sensor_msgs::PointCloud2Modifier::setPointCloud2FieldsByString ( int  n_fields,   ...  )

inline

Function setting some fields in a PointCloud and adjusting the internals of the PointCloud2.

Parameters

n_fields

the number of fields to add. The fields are given as strings: "xyz" (3 floats), "rgb" (3 uchar stacked in a float), "rgba" (4 uchar stacked in a float)

Returns

void

WARNING: THIS FUNCTION DOES ADD ANY NECESSARY PADDING TRANSPARENTLY
