   For a function of three variables, a level set is a surface in three-dimensional space that we will call a level surface. For a constant value c c in the range of f(x, y, z) f (x, y, z), the level surface of f f is the implicit surface given by the graph of c = f(x, y, z) c = f (x, y, z).

   The following diagram shows the level surfaces \[f(x,y,z) = x^2 + y^2 - x^2 = k\] for various \(k\) values. The level surfaces are hyperbolas of one or two sheets, depending on the values of \(k\). Nevertheless, the value of \(f(x,y,z)\) stays the same at each points on a level surface.

   Graph the level surface equation by adding an Implicit Surface from the Add to graph menu and entering the equation for the level surface. If the surfaces are complicated enough, you may not have a choice.

   Example 1: The graph of $z=f(x,\,y)$ as a surface in $3$-space can be regarded as the level surface $w = 0$ of the function $w(x,\,y,\,z) = z - f(x,\, y)$. Example 2: Spheres $x^2+y^2+z^2 = r^2$ can be interpreted as level surfaces $w = r^2$ of the function $w = x^2+y^2+z^2$.

   Nov 21, 2021 · Using CalcPlot3D to Visualize a Level Surface. Often the level surfaces are too complex to graph enough of them, so using a computer program such as CalcPlot3D is the way to go. If you just set the function equal to \(a\), a slider will automatically be created so you can just dynamically observe the level surfaces.

   How to dynamically observe a level surface?

   • If you just set the function equal to a a, a slider will automatically be created so you can just dynamically observe the level surfaces. Below is the dynamic computer plot of the level surface for f(x, y, z) = sin(3x) +y2 −z2 f (x, y, z) = sin (3 x) + y 2 − z 2. You can also explore further by changing the equation.
