Details

This example is very similar to implicit_surface.cpp; however, instead of extracting a surface from a quad tessellation of a hexahedrona we extract the surface from a tessellation of a pyramids. Why use pyramids instead of hexahedrona? In the example implicit_surface.cpp all of the underlying cells are the same size, and thus no gaps occur in the extracted level set (the surface). In this example we have cells that vary a great deal in size.

This example demonstrates scratch made cell predicates, and uses them to increse sample resolution on parts of the surface that are particularly difficlut to extract.

This surface is defined by the zeros of the following polynomial

\[ x^2-y^2*z^2+z^3 \]
