Line Based Iso-Contouring
← Iso-Contouring Example | ● | Marching Quads Algorithm →
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.
