...is Ax + By + Cz + D = 0.
The vector <A, B, C> is a normal vector of the plane. My question is: does the value of D have any geometric significance/interpretation?
I have an algorithm (that I didn't write myself) to evaluate the best-fit plane for a set of points in R3, and the value of D is coming back extremely large (10^20 or something obviously ridiculous). I wonder if D is just a mathematical artifact and I shouldn't worry, or if there is a problem with the algorithm (or my usage of it).
I don't think D should be that large based on the equation for distance between a point (x0, y0, z0) and a plane Ax + By + Cz + D, which is
D = abs(A*x0 + B*y0 + C*z0+ D) / sqrt(A^2 + B^2 + C^2)
My values of A, B, and C are all -1<value<1, but D is so big that it will completely dominate that expression.
Maybe this is a junior question and this thread should be re-categorized as such.
Thanks
