Can anybody verify the formula of Kimberlin on http://mathworld.wolfram.com/Circumcircle.html?
I am unable to proof this. I also failed numerically. It seems that
the formula just describes an ellipse through the corners, but not the
circumcircle.

The formula of Kimberlin is correct.

I found my error. The trilinear coordinates in this formula must be
normalized.
