Quite a while back I asked for help in computing the equation of a circle
from three known points, and I received very useful (and ultimately
successful) assistance from several people. In addition, my searches led me
to a piece of software that handled the calculations for me, making my job
that much easier.
So here's my next question: I now have four non-coplaner points and I need
to derive the sphere that they describe. I'm not having particular luck in
running through the equations because I get bogged-down in my liberal arts
math ignorance. Does someone know of a program that will compute the
equation of a sphere from four points?
Thanks muchly.
Dave!

| (...) A quick search reveals: (URL) reveals that: (x - A)^2 + (y - B)^2 + (z - C)^2 = R Where A,B,C = the x,y,z coordinates that the circle is centered around, and R is the radius you're looking for. Theoretically (tho I haven't tried), you could (...) (21 years ago, 15-Apr-03, to lugnet.off-topic.geek)
