bool polyfem::io::OBJReader::read ( const std::string  obj_file_name, std::vector< std::vector< double > > &  V, std::vector< std::vector< double > > &  TC, std::vector< std::vector< double > > &  N, std::vector< std::vector< int > > &  F, std::vector< std::vector< int > > &  FTC, std::vector< std::vector< int > > &  FN, std::vector< std::vector< int > > &  L  )

static

Read a mesh from an ascii obj file.

Fills in vertex positions, normals and texture coordinates. Mesh may have faces of any number of degree.

Parameters

[in]	obj_file_name	path to .obj file
[out]	V	double matrix of vertex positions
[out]	TC	double matrix of texture coordinates
[out]	N	double matrix of corner normals #N by 3
[out]	F	F list of face indices into vertex positions
[out]	FTC	F list of face indices into vertex texture coordinates
[out]	FN	F list of face indices into vertex normals
[out]	L	list of polyline indices into vertex positions

Returns

true on success, false on errors

Eigen Wrappers of read_obj.

@retruns These will return true only if the data is perfectly "rectangular": All faces are the same degree, all have the same number of textures/normals etc.
