Check out pg 15 of the tutorial PDF.
Non-linear scale
#declare P = function {x*x + y*y + z*z - 1}
isosurface {
function {P(x, y*(1.05-y/5), z)}
....
A non-linear stretch has turned this sphere into something like a hen's egg. The
sphere is stretched more as y
becomes larger, and compressed more as y becomes more negative.
