Detailed Description

A concrete class to read an ASCII Tecplot file.

vtkTecplotReader parses an ASCII Tecplot file to get a vtkMultiBlockDataSet object made up of several vtkDataSet objects, of which each is of type either vtkStructuredGrid or vtkUnstructuredGrid. Each vtkDataSet object maintains the geometry, topology, and some associated attributes describing physical properties.

Tecplot treats 3D coordinates (only one or two coordinates might be explicitly specified in a file) as varaibles too, whose names (e.g., 'X' / 'x' / 'I', 'Y' / 'y' / 'J', 'Z' / 'z' / 'K') are provided in the variables list (the 'VARIABLES' section). These names are then followed in the list by those of other traditional variables or attributes (node- based and / or cell-based data with the mode specified via token 'VAR LOCATION', to be extracted to create vtkPointData and / or vtkCellData). Each zone described afterwards (in the 'ZONE's section) provides the specific values of the aforementioned variables (including 3D coordinates), in the same order as indicated by the variable-names list, through either POINT-packing (i.e., tuple-based storage) or BLOCK-packing (component-based storage). In particular, the first / description line of each zone tells the type of all the constituent cells as the connectivity / topology information. In other words, the entire dataset is made up of multiple zones (blocks), of which each maintains a set of cells of the same type ('BRICK', 'TRIANGLE', 'QUADRILATERAL', 'TETRAHEDRON', and 'POINT' in Tecplot terms). In addition, the description line of each zone specifies the zone name, dimensionality information (size of each dimension for a structured zone), number of nodes, and number of cells. Information about the file format is available at http://download.tecplot.com/360/dataformat.pdf.

Warning: vtkTecplotReader is currently a simplified ASCII Tecplot reader and some functionalities (e.g., extraction of sections 'GEOMETRY', 'TEXT', and 'DATA SETAUXDATA', access to multiple time steps, in addition to the construction of vtkRectilinearGrid and vtkImageData objects) are not supported.

Thanks:: This class is a VTK implementation of VisIt's ASCII Tecplot reader.

virtual int vtkTecplotReader::FillOutputPortInformation	(	int	port,

	)

protectedvirtual

Fill the output port information objects for this algorithm. This is invoked by the first call to GetOutputPortInformation for each port so subclasses can specify what they can handle.

staticprotected

A callback function registered with the selection observer.

void vtkTecplotReader::Init ( )

protected

This function initializes the context. Note that the Tecplot file name must NOT be addressed (either specified or inited) in this function. It is addressed in constructor, destructor, and SetTecplotFile() only.

void vtkTecplotReader::GetDataArraysList ( )

protected

Get the data arrays list from the tecplot file header.

void vtkTecplotReader::ReadFile ( vtkMultiBlockDataSet * multZone )
