Example Input Files & VisTrails Pipelines

Whitworth's (1981) Isothermal Free-Energy Surface

This is one example of an input data file that we have successfully used to generate a useful interactive rendering within VisTrails. The file illustrates VTK's Simple Legacy Format and the POLYDATA dataset format. To aid in implementation, we present the full ascii dataset, the resulting rendered image, and a screen shot of the VisTrails pipeline that was used to generate the image. This example (G) is very similar to the "Cube example" that is provided in §15.3 of the VTK User's Guide, authored and published by Kitware, Inc. (see especially pp. 331-332) and is one of many "simple cube" examples that have been discussed in detail in our accompanying Simple Cube Tutorial. A list of other example input data files is provided near the end of the tutorial.
