I prefer isosurfaces myself, though they currently require a patched
version of POV. I mean, which is easier? This:
quartic{
< 0, 0, 0, 0, 0, 0, 0,
xxzz, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0,
0, 0, yyzz, 0, 0, 0, 0,
0, 0, 0, 0, zz, 0, const >
...
or this:(Not exactly the same as your function, but it should give you
the general idea)
isosurface {
function {z - 1/sqrt(sqr(x) + sqr(y) + 0.01)}
threshold 0
...
