I just had a student come in with an interesting request. He wants to contour a dataset represented in terms of r and theta, in other words, in polar coordinates. Has anyone an algorithm or a pointer to something appropriate in the literature? I suppose I could hack something up if I needed to but I'd appreciate not having to reinvent the wheel. spl (the p stands for polar coordinates) -- Steve Lamont, SciViGuy -- (408) 646-2752 -- a guest at network.ucsd.edu -- NPS Confuser Center / Code 51 / Naval Postgraduate School / Monterey, CA 93943 "The only way to deal with exploiters is to terrorize the bastards." - The late Congressmember Phillip Burton

The NCAR graphics subroutine package will contour data in polar coordinates (or apply about any other transformation you can program). The method is not documented in the users' manuals, but you may be able to contact them directly for information Steve Masters stevem@hal.CSS.GOV ENSCO, Inc. Melbourne, FL 32940 (407) 254 4122
