We're looking for an inexpensive library (or interactive software) for the IRIS 31XX that will do 3-D surface fitting of xyz data, has good 3-D displays (line hiding, perspective views of 3-D meshes), and does contouring. What does the rest of the world use? Any suggestions or knowledge of software that meets part of or all of the above requirements at a reasonable price would be appreciated. We're familiar with some products, e.g. Dynamic Graphics SDL/SGL libraries, but these don't fit our budget. Thanks. L. Ryan (ryanle@pucc)

We use PLOT3D, SURF, RIP, GAS, and ARCgraph. PLOT3D is a graphics program for displaying computational fluid dynamics grids and flow solutions. However, the creative user can use it form more than just this. SURF allows the user to input grid and solution files that are in PLOT3D format and interactively build a 3D model consisting of wirefram, shaded and function mapped parts. PLOT3D is more versatile than SURF, but has a more limited color map. RIP (Remote Interactive Particle-tracer) is a distributed graphics program and is specifically used for post processing CFD data sets. I haven't used this and I think it runs on a CRAY-2 and uses the IRIS as the display device. GAS (Graphics Animation System) is a package developed for the support of the CFD work at NASA-Ames. These are all FREE software from NASA-Ames available only to sites in the U.S. If you have the IRIS Software Exchange Catalog there is information there on how to get the software. If not send E-mail to pierce@prandtl.nas.nasa.gov or call him at (415) 694-4492 to see about getting a copy of PLOT3D. GAS: RIP: Gordon Bancroft, Fergus Merritt Stuart E.

ARCgraph is a library of graphics subroutines accessable from both FORTRAN and C. I hope this is of some help. If you have any questions just ask.
