 Closed-curve B-spline algorithm needed
 Help!

Subject: Closed-curve B-spline algorithm needed
Date: 17 Mar 86 08:01:28 PST (Mon)


I am looking for a reasonably efficient algorithm for computing uniform
periodic B-splines to approximate closed curves from a set of "control
points".  My first choice would be a reference to a good article or book
describing an algorithm in sufficient detail to allow straightforward
coding, but I would also accept actual code in any high-level (i.e., not
assembly) language.

Please help me find the name and address of the maker of the Eidiphor
very large screen video projection systems. I need some info on current
products, and can't find the name.  May be European.  The projectors
use schlieren optics and xexon lamps to project full color video on
screens over 50 feet diag.  Thanks in advance for any assistance.  Mail
to me directly : cater@mcc. Thanks, y'all.
