KochCurve

KochCurve[n]

gives the line segments representing the n^(th)-step Koch curve.

KochCurve[n,{θ1,θ2,}]

takes a series of steps of unit length at successive relative angles θi.

KochCurve[n,{{r1,θ1},{r2,θ2},}]

takes successive steps of lengths proportional to ri.

Details and Options

  • KochCurve is also known as Koch snowflake.
  • KochCurve[n] is generated from the unit interval by repeatedly removing the middle third of the subsequent cells and replacing it with a triangle. »
  • KochCurve[n] is equivalent to KochCurve[n,{0,60 °,-120 °,60 °}].
  • KochCurve takes a DataRange option that can be used to specify the range the coordinates should be assumed to occupy.
