[edit] Summary

Graph of gravity well. Above: Distortion of space-time. Below: Gravitational potential function.

Asymptote source code:

import graph3;

typedef real fun(real);

fun Phi(real R, real GM_R, real shift=0) {
  return new real(real r) {
    real r_R = abs(r) / R;
    if (r_R >= 1)
      return -GM_R / r_R + shift;
    else
      return 0.5 GM_R * (r_R^2 - 3) + shift;
  };
}

typedef real fun2(pair);
fun2 revolve(fun f) { return new real(pair z) { return f(abs(z)); }; }

size(300,0);
currentprojection=perspective(0,20,4);
add(surface(revolve(Phi(2,7)), nsub=4, (-12,-12), (12,12), nx=20, light=O));
draw(graph(Phi(2,7,-10),-24,24));
