Parametric Koch snowflakes

The Koch snowflake is a fractal curve which was first described by Helge von Koch in 1904. The sequence of Koch curves starts with a triangle and successively replaces each side with a new side with added triangle.

This OpenSCAD code uses functions from a larger tiling library based on the use of perimeter descriptions in the form of {sidelength, angle} and Turtle geometry to generate the corresponding polygon.

Due to limits on recursion, we are limited to order 4 curves but since these have 768 sides and order 5 has 3092 sides (3 * 4^N) this is probably high enough for printing or laser cutting.

The code can be modified to generate other fractal curves . For example replacing the Koch side perimeter [240,60,240,60] with [120,300,120,60] yields the Koch antisnowflake
