## Line Based Iso-Contouring

Geometrically the set of points with the same value (the so called iso value) is a line.

For a 2D regular data grid an iso line is the set of line segments extracted from each cell of the grid.

A set of extracted iso lines is also called a level set.

Important property: Iso lines are water-tight and they do not intersect each other.
