This week's book giveaway is in the Java 8 forum. We're giving away four copies of Java 8 in Action and have Raoul-Gabriel Urma, Mario Fusco, and Alan Mycroft on-line! See this thread for details.

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.

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
