Member Function Documentation

parse_header_()

void volcart::io::PLYReader::parse_header_ ( )

private

Parse the PLY header.

The header defines the expected layout for the body of the PLY file, including the count for each element (e.g. vertices, faces, etc). This information is stored in elementsList_ and used when reading in faces and vertices.

Member Data Documentation

elementsList_

std::vector<std::string> volcart::io::PLYReader::elementsList_

private

List of elements parsed from the header

Definition at line 64 of file PLYReader.hpp.

faceList_

std::vector<SimpleMesh::Cell> volcart::io::PLYReader::faceList_

private

Temporary face list

Definition at line 60 of file PLYReader.hpp.

hasLeadingChar_

bool volcart::io::PLYReader::hasLeadingChar_ = true

private

Tracks if there is a leading character in front of each face line. This character tells how many vertices are in that face.

Definition at line 78 of file PLYReader.hpp.

hasPointNorm_

bool volcart::io::PLYReader::hasPointNorm_ = false

private

Track if there are vertex normals

Definition at line 81 of file PLYReader.hpp.

inputPath_

filesystem::path volcart::io::PLYReader::inputPath_

private

Input file path

Definition at line 52 of file PLYReader.hpp.

line_

std::string volcart::io::PLYReader::line_

private

Line currently being parsed

Definition at line 58 of file PLYReader.hpp.

numFaces_

int volcart::io::PLYReader::numFaces_

private

Number of faces expected in the parsed mesh

Definition at line 68 of file PLYReader.hpp.

numVertices_

int volcart::io::PLYReader::numVertices_

private

Number of vertices expected in the parsed mesh

Definition at line 66 of file PLYReader.hpp.

outMesh_

ITKMesh::Pointer volcart::io::PLYReader::outMesh_

private

Output mesh

Definition at line 56 of file PLYReader.hpp.

plyFile_

std::ifstream volcart::io::PLYReader::plyFile_

private

Input file stream

Definition at line 54 of file PLYReader.hpp.

pointList_

std::vector<SimpleMesh::Vertex> volcart::io::PLYReader::pointList_

private

Temporary vertex list

Definition at line 62 of file PLYReader.hpp.

properties_

std::map<std::string, int> volcart::io::PLYReader::properties_

private

Maps positions in a string to a particular attribute

Definition at line 72 of file PLYReader.hpp.

skippedLine_

std::vector<int> volcart::io::PLYReader::skippedLine_

private

Number of lines used by the elements we can't handle

Definition at line 70 of file PLYReader.hpp.
