[comp.graphics] Questions [1] Cir. DDA [2] IEEE Symp

smiller@wet.UUCP (Gregory Shane Miller) (08/21/90)

         I have two questions - Can you help?

         [1] Circular DDA

             R.A. Earnshaw  edited (J.E. Bresenham and M.L.V. Pitteway
             directed) a  book  called   "Fundamental  Algorithms  for
             Computer Graphics" in 1985.  The book is a compilation of
             papers from a meeting held in England.

             The book contains an article on a circular DDA (submitted
             by Hong Toa [from Northwestern Polytechnical  University,
             Xian China]).

             I have  a  question about that article, but have *little*
             hope in reaching Mr. Hong  Toa.   Therefore, I am looking
             for the address (electronic or otherwise)  of the editors
             or directors.

             At the   time   of   publication,  Earnshaw  was  at  the
             University of Leeds (United  Kingdom).  Does anybody know
             where these guys are?

             Does anybody have the following?

                 B.M. Chazelle   and   H.  Edelsbrunner,  "An  optimal
                 algorithm for intersecting line segments", Proc 29th
                 IEEE Symp. on Foundations  of  Computer  Science (Oct
                 1988)

             Email me with your terms ... I need that article bad!

         ---------------- Thanks!
