Detailed Description

A general purpose PLY file reader.

This class is internally used by PointCloudIO, SurfaceMeshIO, and GraphIO. Client code should use PointCloudIO, SurfaceMeshIO, and GraphIO.

Member Function Documentation

num_instances()

static std::size_t num_instances ( const std::string & file_name, const std::string & element_name )

static

A quick check of the number of instances of a type of element.

The typical use is to determine if a PLY file stores a point cloud, a graph, or a surface mesh. Internally it reads the ply file header only (without parsing the entire file).

Parameters

file_name	The input file.
element_name	A string denoting the type of the element to be checked. Typical elements are "vertex", "face", and "edge".

Returns

The number of instances of the element.

Examples

Tutorial_203_Viewer_wxWidgets/main.cpp, and Tutorial_204_Viewer_Qt/main.cpp.

read()

bool read	(	const std::string &	file_name,
		std::vector< Element > &	elements )

Reads a PLY file and stores the model as a set of elements.

Parameters

file_name	The name of the PLY file to read.
elements	The vector to store the read elements.

Returns

True if the file was successfully read, false otherwise.
