koch snowflake zoom

Hence, the length of the curve after n iterations will be (4/3)n times the original triangle perimeter and is unbounded, as n tends to infinity. It's possible to continuously zoom into a fractal and experience the same behavior. The value for area asymptotes to the value below. Your email address will not be published. The Koch snowflake is the limit approached as the above steps are followed indefinitely. https://www.khanacademy.org/.../koch-snowflake/v/koch-snowflake-fractal A Koch curve–based representation of a nominally flat surface can similarly be created by repeatedly segmenting each line in a sawtooth pattern of segments with a given angle.[4]. Starting with a unit square and adding to each side at each iteration a square with dimension one third of the squares in the previous iteration, it can be shown that both the length of the perimeter and the total area are determined by geometric progressions. However, such a tessellation is not possible using only snowflakes of one size. What is a fractal? No matter how far down we recurse, the shape will never grow outside this hexagon, so it can't keep growing forever!). The Koch Snowflake fractal is, like the Koch curve one of the first fractals to be described. . When we first start out, there are 3 sides to the triangle, each of length one unit. The Koch snowflake can be constructed by starting with an equilateral triangle, then recursively altering each line segment as follows: The first iteration of this process produces the outline of a hexagram. The Koch snowflake (also known as the Koch curve, Koch star, or Koch island ) is a fractal curve and one of the earliest fractals to have been described. An example Koch Snowflake is shown on the right. The areas enclosed by the successive stages in the construction of the snowflake converge to 8/5 times the area of the original triangle, while the perimeters of the successive stages increase without bound. Now all the exponents are the same order and we can combine them and pull the 4 inside each of the terms. In each iteration a new triangle is added on each side of the previous iteration, so the number of new triangles added in iteration n is: The area of each new triangle added in an iteration is 1/9 of the area of each triangle added in the previous iteration, so the area of each triangle added in iteration n is: where a0 is the area of the original triangle. If the Thue–Morse sequence members are used in order to select program states: the resulting curve converges to the Koch snowflake. 11 We are now left with a shape comprised of four equal length segments. The typical way to generate fractals is with recursion. The total new area added in iteration n is therefore: The total area of the snowflake after n iterations is: Thus, the area of the Koch snowflake is 8/5 of the area of the original triangle. I'll define the infinite series (shown in gold below) to be the letter G. Here's a clever trick. Consequently, the snowflake encloses a finite area, but has an infinite perimeter. {\displaystyle {\frac {11{\sqrt {3}}}{135}}\pi .} Only upper and lower bounds have been invented.[5]. The Koch Curve has the seemingly paradoxical property of having an infinitely long perimeter (edge) that bounds a finite (non-infinite) area. Here is an animation showing the effect of zooming in to a Koch curve. If you zoom into a fractal, you get see a shape similar to that seen at a higher level (albeit it at smaller scale). Each iteration multiplies the number of sides in the Koch snowflake by four, so the number of sides after n iterations is given by: If the original equilateral triangle has sides of length s, the length of each side of the snowflake after n iterations is: an inverse power of three multiple of the original length. The first stage is an equilateral triangle, and each successive stage is formed from adding outward bends to each side of the previous stage, making smaller equilateral triangles. Here is the simple equation for the length of the sides at each depth: You can see as n increases, the length is unbounded. To first understand the relationship, we first need to understand a Thue-Morse sequence! Each iteration creates four times as many line segments as in the previous iteration, with the length of each one being 1/3 the length of the segments in the previous stage. If we assume that the length of each side of the starting triangle is one unit. Fractals are never-ending infinitely complex shapes. Its fractal dimension equals, Extension of the quadratic type 1 curve. The Thue–Morse sequence (or Prouhet–Thue–Morse sequence), is an infinite binary sequence obtained by starting with 0 and successively appending the Boolean complement of the sequence obtained thus far. I think you can see where this is going. © 2009-2016 DataGenetics    Privacy Policy, If we encounter a one, we step forward one space, then turn 60°, Combining these, the first 2 elements are, Combining these, the first 4 elements are, Combining these, the first 8 elements are. Below is a graph showing how the area of the snowflake changes with increasing fractal depth, and how the length of the curve increases. Fields marked with * are required. Does the area asymptote to a certain value? In order to find the sum, it helps if we clean this up a little. draw an equilateral triangle that has the middle segment from step 1 as its base and points outward. Expressed in terms of the side length s of the original triangle, this is:[6], The volume of the solid of revolution of the Koch snowflake about an axis of symmetry of the initiating equilateral triangle of unit side is Click here to receive email alerts on new articles. Go to step 1. In other words, three Koch curves make a Koch snowflake. Zoom + Pan. To generate a Koch curve we start off with a line of unit length. Let's keep with the notation that the length of the side of initial triangle is s. The area of the first iteration is simply the area of the base triangle. [8] Koch snowflakes and Koch antisnowflakes of the same size may be used to tile the plane. This is a little more complicated to calculate. Next we divide this line into three equal segments. Lets apply these rules to T4 = 0110100110010110, and see what we get …. To create the Koch snowflake, one would use F--F--F (an equilateral triangle) as the axiom. To make a snowflake, instead of starting with just one line, we start with three similar lines, arranged as an equilateral triangle, and apply the process in parallel to each of three segments. 2) Draw equilateral triangles out of each of the middle segments. 135 The fractal dimension of the Koch curve is ln 4/ln 3 ≈ 1.26186. 3 "Sur une courbe continue sans tangente, obtenue par une construction géométrique élémentaire", "Static friction between rigid fractal surfaces", "IX Change and Changeability § The snowflake", Application of the Koch curve to an antenna, A WebGL animation showing the construction of the Koch surface, "A mathematical analysis of the Koch curve and quadratic Koch curve", https://en.wikipedia.org/w/index.php?title=Koch_snowflake&oldid=985772209, Articles with unsourced statements from September 2019, Creative Commons Attribution-ShareAlike License. If we imagine that each of these four line segments are, themselves, made up from smaller versions of themselves, the curve starts to form …. The curve gets ever increasingly longer, more convulated, and 'twisty', even though the geometric distance between the end points remains the same. Next we need to calculate the area inside the triangles. The total area covered at the nth iteration is: while the total length of the perimeter is: which approaches infinity as n increases.
