Standard_Boolean Read (const TCollection_AsciiString &theFile, const Message_ProgressRange &theProgress)
 Reads data from OBJ file. Unicode paths can be given in UTF-8 encoding. Returns true if success, false on error or user break. More...
 
Standard_Boolean Probe (const TCollection_AsciiString &theFile, const Message_ProgressRange &theProgress)
 Probe data from OBJ file (comments, external references) without actually reading mesh data. Although mesh data will not be collected, the full file content will be parsed, due to OBJ format limitations. More...

const RWMesh_CoordinateSystemConverterTransformation () const
 Return transformation from one coordinate system to another; no transformation by default. More...
 
void SetTransformation (const RWMesh_CoordinateSystemConverter &theCSConverter)
 Setup transformation from one coordinate system to another. OBJ file might be exported following various coordinate system conventions, so that it might be useful automatically transform data during file reading. More...
