[comp.graphics] Need contouring algorithm

kemp@umn-cs.CS.UMN.EDU (Stuart R. Kemp) (07/06/89)

I have some data in the form of (x,y,z) points that I
would like to display with a contour map. I have an
algorithm that will plot a contour, but it considers
the data row at a time. What I would like is an algorithm
that traces out each contour line. If you know where I can
find such an algorithm, or if you have on yourself, please
let me know via email.

Thanks,

ACM algorithm 626 probably does what you want.

Send e-mail to netlib@research.att.com with null subject and the following
two lines
send index
send 626 from TOMS

... and an automatic mailer will mail you the algorithm and index of other
goodies.
