Member Function Documentation

read() [1/3]

int pcl::IFSReader::read	(	const std::string &	file_name,
		pcl::PCLPointCloud2 &	cloud,
		int &	ifs_version
	)

Read a point cloud data from an IFS file and store it into a pcl/PCLPointCloud2.

Parameters

[in]	file_name	the name of the file containing the actual PointCloud data
[out]	cloud	the resultant PCLPointCloud2 blob read from disk
[out]	ifs_version	the IFS version of the file (either IFS_V1_0 or IFS_V1_1)

Returns

• < 0 (-1) on error
• == 0 on success

read() [2/3]

template<typename PointT >

int pcl::IFSReader::read ( const std::string &  file_name, pcl::PointCloud< PointT > &  cloud  )

inline

Read a point cloud data from an IFS file, and convert it to the given template pcl::PointCloud format.

Parameters

[in]	file_name	the name of the file containing the actual PointCloud data
[out]	cloud	the resultant PointCloud message read from disk

Returns

• < 0 (-1) on error
• == 0 on success

read() [3/3]

int pcl::IFSReader::read	(	const std::string &	file_name,
		pcl::PolygonMesh &	mesh,
		int &	ifs_version
	)

Read a point cloud data from an IFS file and store it into a PolygonMesh.

Parameters

[in]	file_name	the name of the file containing the mesh data
[out]	mesh	the resultant PolygonMesh
[out]	ifs_version	the IFS version of the file (either IFS_V1_0 or IFS_V1_1)

Returns

• < 0 (-1) on error
• == 0 on success

readHeader()

int pcl::IFSReader::readHeader	(	const std::string &	file_name,
		pcl::PCLPointCloud2 &	cloud,
		int &	ifs_version,
		unsigned int &	data_idx
	)

Read a point cloud data header from an IFS file.

Load only the meta information (number of points, their types, etc), and not the points themselves, from a given IFS file. Useful for fast evaluation of the underlying data structure.

Parameters

[in]	file_name	the name of the file to load
[out]	cloud	the resultant point cloud dataset (only header will be filled)
[out]	ifs_version	the IFS version of the file (IFS_V1_0 or IFS_V1_1)
[out]	data_idx	the offset of cloud data within the file

Returns

• < 0 (-1) on error
• == 0 on success
