Fractal interpolation of polygons

[edit]

Fractal interpolation of polygons is a local procedure which applies to polyline model of curve. This model represents non-local features of curve, or shape. The curve created by fractal interpolation has fine structure (texture) which is fully matched with it's shape. For flat curve fractal interpolation can be easily described using complex coordinates. Let zn be vertex of polygon. Fractal interpolation insert two point zn+1/3 and zn+2/3 between zn and zn+1, such that


Example: fractal "Tree of Life"
