Example Input Files & VisTrails Pipelines

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) 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 is provided near the end of our accompanying Simple Cube Tutorial.
