Marching Triangles Algorithm

A variant of the marching cells algorithm, which is computationally less complex is the reduction of the problem to iso line extraction from triangles.

Each cell is split into two triangles (2 symmetrical possibilities):

The reduction to triangles resolves the ambiguity of the original iso line extraction algorithm (at the expense of disrespecting saddle points).
