4 Points on a Bowl.surface
With a matrix operation, we determine the center of a bowl and its radius, so that 4 given points are located on its surface.
You can shift the 4 points P_0, P_1, P_2 and P_3 and see, how the resulting bowl will change.
For a better visualization, the 3 circles through the 3 triple combinations are drawn, also.
Have much fun
