Ryan,

The actual implementation of ContourPlot3D can be found in the 
Graphics`ContourPlot3D` package. The Help section of ContourPlot3D states:
ContourPlot3D works by dividing the three-dimensional space into cubes and 
deciding if the surface intersects each cube. If the surface does intersect 
a cube, ContourPlot3D will subdivide this cube further,and so on.

On the other hand, ListContourPlot is a built-in function, and so you won't 
be able to examine a package to find its implementation.
