The surface in above image is a portion of the graph of
some mathematical equation.

Let's do some brainstorming:
Can you guess what's inside the surface?

A funny 3D image:

A funny curve:

The above graphics were created completely using math formulas and math softwares.

Hint:
Consider the intersection of a horizontal plane with the surface.

The intersection consists of a family of funny curves.
(An example curve is shown below. It has nothing to do with the answer.)

Cut off the upper surface above the horizontal plane to get a funny 3D image.

(This curve is obtained from another surface.)
