Member Data Documentation

m_model

Model& Slic3r::IO::TMFParserContext::m_model

Model to receive objects extracted from an 3MF file.

m_object

ModelObject* Slic3r::IO::TMFParserContext::m_object

Current object allocated for an model/object XML subtree.

m_object_vertices

std::vector<float> Slic3r::IO::TMFParserContext::m_object_vertices

Vertices parsed for the current m_object.

m_objects_indices

std::map<std::string, int> Slic3r::IO::TMFParserContext::m_objects_indices

Current Expat XML parser instance.

m_path

std::vector<TMFNodeType> Slic3r::IO::TMFParserContext::m_path

Current parsing path in the XML file.

m_value

std::string Slic3r::IO::TMFParserContext::m_value[3]

Generic string buffer for metadata, etc.

m_volume

ModelVolume* Slic3r::IO::TMFParserContext::m_volume

Volume allocated for an model/object/mesh.

m_volume_facets

std::vector<int> Slic3r::IO::TMFParserContext::m_volume_facets

Faces collected for all volumes of the current object.
