Detailed Description

Implementation of a Reader for vtk/vtu files using the vtk-library.

The functions can only be used when t8code is linked with the vtk-library.

Function Documentation

t8_cmesh_vtk_reader()

t8_cmesh_t t8_cmesh_vtk_reader	(	const char *	filename,
		const int	partition,
		const int	main_proc,
		sc_MPI_Comm	comm,
		const vtk_file_type_t	vtk_file_type
	)

Given a filename to a vtkUnstructuredGrid or vtkPolyData read the file and construct a cmesh.

This is a two stage process. First the file is read and stored in a vtkDataSet using t8_vtk_reader and t8_file_to_vtkGrid. In the second stage a cmesh is constructed from the vtkDataSet using t8_vtkGrid_to_cmesh.

Both stages use the vtk-library, therefore the function is only available if t8code is linked against VTK.

Parameters

[in]	filename	The name of the file
[in]	partition	Flag if the constructed mesh should be partitioned
[in]	main_proc	The main reading processor
[in]	comm	An mpi-communicator
[in]	vtk_file_type	A vtk-filetype that is readable by t8code.

Returns

A committed cmesh.
