  Plane passing through 3 points

Hello,

I have 3 points A, B and C
I would like the "plane" object to pass through these three points.

It is easy to determine the equation of a plane that passes through
these three points. We obtain this equation : ax + by + cz + d = 0

I try to do : plane { <a, b, c>, d }

but the plane does not pass through the points.


Documentation at <http://www.povray.org/documentation/view/3.7.1/297/>
indicates that the object "plane { <A, B, C>, D }" represent the plane
defined by : A*x + B*y + C*z - D*sqrt(A^2 + B^2 + C^2) = 0

... I must be dumb but I can't make the link with my plan equation.


A little help ?
