Using the gts_isosurface_cartesian() function, it is possible to build a triangulated isosurface of a given user-defined function. As its name indicates this function assumes that the values of the user-defined function are defined for points located on a regular cartesian grid described by the GtsCartesianGrid parameter.

Iso surfaces are a three dimensional visualization tool that show a value as well as the physical shape of the According to this rule, at least one isosurface cell of a closed isosurface can be found by traversing cells across the graph connecting all extreme points in a volume. Also, at least one isosurface cell of an open isosurface can be found by traversing cells on the boundary of a volume. Fig. 5.5 shows the overview of the above idea.
