4 Points on a Bowl / 4 Punkte auf einer Kugel

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
