Does anybody know of some easy to use code that takes math functions and renders them on the Iris in 3D complete with color, lighting and shading? I am working with power functions of the type (1/x)^-A. I want to view Y as a function of X for a family of A's with X varying in the "third" dimension. Any suggestions? I tried playing with wavefront's Visualizer with no success. Before I start writing Gl to do this, I just know this must have been done before....any suggestions will be most appreciated....I'll post any solutions e-mailed to me.... !nuchat!texhrc!mjz

If I needed to plot a function like you suggest and needed a quick look, I would right a quick program to generate a file with all the points in it and then display it with PLOT3D and/or SURF. These are two programs written at Ames, free for U.S. dissemination only. They are also suppose to be releasing some new software called FAST. -- Brent L.

Yep, take a look at Mathematica from Wolfram Research :-) Mathematica is available through your SGI sales rep. Our implementation is rather impressive, especially if you have used Mathematica on other platforms. For more information, contact your sales rep or me. -- Mike -- Michael I.

Mathematica on the IRIS provides only a command line interface. There is no support for the editing of notebooks; unlike "other platforms" such as the NeXT and the Mac. Remote users of Mathematica have access only to the Postscript graphics. The shaded-graphics of the GL cannot be used remotely. Mathematica on the IRIS is _adequate_. -- -- Jeff Hultquist hultquis@nas.nasa.gov NASA - Ames Research Center (415) 604-4970 Disclaimer: "I am not a rocket scientist."

From: hultquis@nas.nasa.gov (Jeff P. M. Hultquist) Newsgroups: comp.sys.sgi Mathematica on the IRIS provides only a command line interface. There is no support for the editing of notebooks; unlike "other platforms" such as the NeXT and the Mac. True; however this is easily worked around. Since I use Mathematica inside of emacs, I have all the editting capability I need. Also, certain shells have built-in command line editting capabilities. I hear your gripe, however, and will look into adding this feature for a future release. With the possible exception of the NeXT, no other UNIX implementation of Mathematica provides this feature. Remote users of Mathematica have access only to the Postscript graphics. The shaded-graphics of the GL cannot be used remotely. By "remotely" you must mean on another IRIS, right? Through the magic of dgl this should be fairly easy to correct in a future release. Of course, what you can do with Mathematica on your console cannot be done *anywhere else* on *any other* platform. Mathematica on the IRIS is _adequate_. Graphics aside, Mathematica on the IRIS blows doors on the NeXT and the Mac in pure computational speed. At a recent trade show, an attendee came by out booth with a formula for a surface which took nearly ten minutes to calculate (and longer to draw) on a NeXT machine. We typed it in for fun, and a Personal Iris computed AND drew the surface in less than two minutes. Apparently you are familiar with the GL extensions. There is NO OTHER implementation of Mathematica which allows the manipulation (i.e. real-time rotations, lighting and shading) of rendered surfaces that can be done on the IRIS. This is the functionality in which Mr. Zeitlin expressed an interest, and I truly believe Mathematica on the IRIS is the best solution for him. Despite the apparent defensive tone of my response, I appreciate your feedback. You raise good points, and they are noted. -- Mike -- Michael I.
