Point Cloud Data (PLY) file format reader.
The PLY data format is organized in the following way: lines beginning with "comment" are treated as comments

Read a point cloud data from a PLY file and store it into a pcl/PCLPointCloud2.
[in] | file_name | the name of the file containing the actual PointCloud data |
[out] | cloud | the resultant PointCloud message read from disk |
[in] | origin | the sensor data acquisition origin (translation) |
[in] | orientation | the sensor data acquisition origin (rotation) |
[out] | ply_version | the PLY version read from the file |
[in] | offset | the offset in the file where to expect the true header to begin. One usage example for setting the offset parameter is for reading data from a TAR "archive containing multiple files: TAR files always add a 512 byte header in front of the actual file, so set the offset to the next byte after the header (e.g., 513). |

Read a point cloud data from a PLY file (PLY_V6 only!) and store it into a pcl/PCLPointCloud2.
PLY_V6 will generate a warning.

[out] | cloud | the resultant PointCloud message read from disk |

virtual |
Read a point cloud data header from a PLY file.
Load only the meta information (number of points, their types, etc), and not the points themselves, from a given PLY file. Useful for fast evaluation of the underlying data structure.
Returns:
[in] | file_name | the name of the file to load |
[out] | cloud | the resultant point cloud dataset (only the header will be filled) |
[in] | origin | the sensor data acquisition origin (translation) |
[in] | orientation | the sensor data acquisition origin (rotation) |
[out] | ply_version | the PLY version read from the file |
[out] | data_type | the type of PLY data stored in the file |
[out] | data_idx | the data index |
[in] | offset | the offset in the file where to expect the true header to begin. One usage example for setting the offset parameter is for reading data from a TAR "archive containing multiple files: TAR files always add a 512 byte header in front of the actual file, so set the offset to the next byte after the header (e.g., 513). |
