This is an example input data file that has been developed based on the structured-points illustration that I found in a tutorial powerpoint presentation posted (circa 2010) [http://www.bu.edu/tech/files/2010/10/VTK-Fall-2010.ppt by Robert Putnam on a Boston University website]; see especially slides 22-25.  The file illustrates VTK's ''Simple Legacy Format'' and the STRUCTURED_POINTS dataset format.  To aid in implementation, we present the full ascii dataset, two resulting rendered images, and a screen shot of the VisTrails pipeline that was used to generate the image.  Note that the image captioned "Point Data" was generated, by default, while the image captioned "Cell Data" was generated after activating the ''SetScalarModeToUseCellData'' method within the '''vtkDataSetMapper''' module.  A list of other example input data files [[User:Tohline/vtk/SimpleCubeTutorial#Other_Example_Input_Files_and_VisTrails_Pipelines|is provided near the end of our accompanying ''Simple Cube Tutorial'']].

This is an example input data file based on a structured-grid illustration that I found on a Cornell University website. The file illustrates VTK's Simple Legacy Format and the RECTILINEAR_GRID dataset format. Because this example uses 47 x 33 x 11 = 17,061 grid points, we provide a pointer to the website where the input file can be accessed, instead of displaying the entire data file here.

To aid in implementation, we present an image of the Cornell configuration and a screen shot of the VisTrails pipeline that was used to generate the image. The data file assigns a scalar value plus a vector velocity to each grid POINT, but it assigns no information to the corresponding grid CELLS.
