Best fitting Line

Hi all! I''m searching for an algorithm for calculating the best fitting line (in 3D) of a couple of points. Any hints? Thanks a lot -------------------------------------------------------- "If it looks good, it is good computer graphics" "If it looks like computer graphics, it is bad computer graphics" Corrail corrail@gmx.at ICQ#59184081

Umm... could you be more specific (I can''t understand your wording). Do you mean, you have two points and you want to define a line (a vector) between them and find its length?

I believe he''s referring to best-fit lines like those used in chart-plotting programs to show a trend. I''m pretty sure the way they do it is by taking the average of the slopes of adjacent points.

Actually, what you''re looking for is called Linear Regression. You can easily adapt the method for 3D.
