cartoreader_lite.low_level.read_mesh¶

This file provides routines to read .mesh files from CARTO3

Functions

`read_mesh_file`(fname)	Reads a single mesh file in CARTO3 mesh format and returns it as a pyvista object
`read_section`(lines)	Reads a single section of the .mesh files
`read_tris`(data)	Converts the dataframe of the TrianglesSection into multiple numpy array
`read_vertices`(data)

cartoreader_lite.low_level.read_mesh.read_section(lines: Iterable[str]) → pandas.core.frame.DataFrame¶

Reads a single section of the .mesh files

Parameters: lines (Iterable[str]) – The lines of the section
Returns: The section data in a dataframe
Return type: pd.DataFrame

cartoreader_lite.low_level.read_mesh.read_tris(data: pandas.core.frame.DataFrame) → Tuple[numpy.ndarray, numpy.ndarray, numpy.ndarray]¶

Converts the dataframe of the TrianglesSection into multiple numpy array

Parameters: data (pd.DataFrame) – The data containing the TrianglesSection
Returns: Returns the triplet (faces [Mx3], normals [Mx3], group-ID [M])
Return type: Tuple[np.ndarray, np.ndarray, np.ndarray]

cartoreader_lite.low_level.read_mesh.read_mesh_file(fname: str) → Tuple[Union[pyvista.core.pointset.UnstructuredGrid, pyvista.core.pointset.PolyData], dict]¶

Reads a single mesh file in CARTO3 mesh format and returns it as a pyvista object

Parameters: fname (str) – Filename of the mesh file
Returns: Returns the constructred mesh from the data, along with the header data as a dictionary
Return type: Tuple[Union[pv.UnstructuredGrid, pv.PolyData], dict]
