getLoadPLYErrorString()

std::string mrpt::utils::PLY_Importer::getLoadPLYErrorString ( ) const

inline

Return a description of the error if loadFromPlyFile() returned false, or an empty string if the file was loaded without problems.

Definition at line 41 of file PLY_import_export.h.

loadFromPlyFile()

bool PLY_Importer::loadFromPlyFile	(	const std::string &	filename,
		CStringList *	file_comments = NULL,
		CStringList *	file_obj_info = NULL
	)

Loads from a PLY file.

Parameters

[in]	filename	The filename to open. It can be either in binary or text format.
[out]	file_comments	If provided (!=NULL) the list of comment strings stored in the file will be returned.
[out]	file_obj_info	If provided (!=NULL) the list of "object info" strings stored in the file will be returned.

Returns

false on any error in the file format or reading it. To obtain more details on the error you can call getLoadPLYErrorString()

PLY_import_set_face_count()

virtual void mrpt::utils::PLY_Importer::PLY_import_set_face_count ( const size_t  N )

protectedpure virtual

In a base class, reserve memory to prepare subsequent calls to PLY_import_set_face.

Implemented in mrpt::maps::CPointsMap, mrpt::opengl::CPointCloudColoured, and mrpt::opengl::CPointCloud.

PLY_import_set_vertex()

virtual void mrpt::utils::PLY_Importer::PLY_import_set_vertex ( const size_t  idx, const mrpt::math::TPoint3Df &  pt, const mrpt::utils::TColorf *  pt_color = NULL  )

protectedpure virtual

In a base class, will be called after PLY_import_set_vertex_count() once for each loaded point.

Parameters

pt_color

Will be NULL if the loaded file does not provide color info.

Implemented in mrpt::maps::CPointsMap, mrpt::maps::CColouredPointsMap, mrpt::opengl::CPointCloudColoured, and mrpt::opengl::CPointCloud.

PLY_import_set_vertex_count()

virtual void mrpt::utils::PLY_Importer::PLY_import_set_vertex_count ( const size_t  N )

protectedpure virtual

In a base class, reserve memory to prepare subsequent calls to PLY_import_set_vertex.

Implemented in mrpt::maps::CColouredPointsMap, mrpt::opengl::CPointCloudColoured, mrpt::maps::CWeightedPointsMap, mrpt::maps::CSimplePointsMap, and mrpt::opengl::CPointCloud.
