Hi All,
I have 8 X and Y points which may or mayn't be linear.I wanted to draw curve which passes through closest points. Can any body expain me? ( example would be great help).
I also like to know if I have 2 points (x1,y1) and (x2,y2), how to draw bezier curve? I was thinking of drawing bezier curve between 2 points and joing that with next curve with (x2,y2) and (x3,y3).
Thanks,
padmashree

You need a resource on numerical methods. I have done
this sort of thing in FORTRAN, but not in a long while.
Java is certainly capable, but I don't believe that
it have any built in support. Try a Google search
for Java and numerical methods or Java and curve fitting.

I also like to know if I have 2 points (x1,y1) and (x2,y2), how to draw bezier curve? I was thinking of drawing
bezier curve between 2 points and joing that with next curve with (x2,y2) and (x3,y3).

The best explanation of beziers that I have seen is
in the O'Reilly book on SVG. There might be good
information in the results of the sbove Google search,
too.
IBM once had a project called NINJA, for Numerically
Intensive Java (or something like that). If it's
still out there, I'd bet there's a lot of good stuff
there.
BTW, my fortune at login on one of my Linux boxes
last week said,
"FORTRAN is for pipe stress freaks and
crystallography weenies."
LOL!
HTH,
Joe
