That is a highly approximate way to do it - which may be fine, but I doubt any floating point errors you get are going to make it worse. > if you > know of another good way to compute the surface of overlapping disks, > I'd be glad to know. Are these "disks" exactly round? If so -- use coordinate geometry to calculate it exactly (or as exactly as floating point allows ;-) ) I just googled: "area of intersecting circles" And got a bunch of hits. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
