I can't tell if you are browsing or have installed openDX. You might see some pictures on the opendx.org gallery (maybe David T. can point out specific examples). If you've installed openDX, there are sample programs with sample data included in the package. Vectors are shown directly with AutoGlyph (as rockets or needles), vector fields with Streamlines or Streaklines. Vector magnitude can be trivially computed and colormapped within DX. Vector gradient can be trivially computed and realized in a number of ways as well. For examples, once you've derived/extracted a scalar quantity from a vectorial input, isosurfaces, plots, colormaps, rubbersheets of a slice through the field, etc. etc. Chris Pelkie Vice President/Scientific Visualization Producer Conceptual Reality Presentations, Inc. 30 West Meadow Drive Ithaca, NY 14850 [EMAIL PROTECTED] (607) 257-8335 or (607) 254-8794
