Draw a randomly colored Sierpinski octagon in C#

Posted on December 8, 2018 by RodStephens

This example draws a randomly colored Sierpinski octagon. It’s basically the same as the example Draw a randomly colored Sierpinski pentagon in C# except it draws an octagon instead of a pentagon. See that example for most of the details. … Continue reading →

Draw a randomly colored Sierpinski pentagon in C#

Posted on October 4, 2018 by RodStephens

The example Draw a colored Sierpinski pentagon in C# lets the user click on the parts of a Sierpinski pentagon to change their colors. Eddie Bole thought it would be interesting to color the larger pentagons in addition to the … Continue reading →

Draw a colored Sierpinski pentagon in C#

Posted on October 1, 2018 by RodStephens

The example Draw a Sierpinski pentagon in C# shows how to draw a Sierpinski pentagon. This example modifies that one so the user can click on pentagons to change their colors. To do that, this program takes a very different … Continue reading →

Draw a Pythagoras tree fractal in C#

Posted on April 27, 2018 by RodStephens

A Pythagoras tree (or Pythagorean tree) is a fractal tree built from squares. It starts with a square that forms the tree’s base. The program then makes the Pythagoras tree by recursively attaching two smaller branches to the original branch. … Continue reading →

Draw a Sierpinski pentagon in C#

Posted on April 25, 2018 by RodStephens

In a Sierpinski pentagon, larger pentagons are recursively divided into five smaller pentagons with a sixth uncolored pentagon in the center. The following picture shows the first four levels of the resulting fractal. For this example, I decided to think … Continue reading →

Draw a Fibonacci word fractal in C#

Posted on December 5, 2017 by RodStephens

This example uses the Fibonacci word to draw a fractal curve. For information on the Fibonacci word, see the post Calculate Fibonacci words in C#. To draw a curve with level N, use Fibonacci word number N. Loop through the … Continue reading →

Calculate Fibonacci words in C#

Posted on November 30, 2017 by RodStephens

You can find Fibonacci words by concatenating previous Fibonacci words much as you calculate the Fibonacci sequence by adding previous values in the sequence. The first two Fibonacci words are: S0 = 0 S1 = 01 The following Fibonacci words … Continue reading →

Draw the Weierstrass function in C#

Posted on September 11, 2017 by RodStephens

The Weierstrass function was discovered by Karl Weierstrass in 1872. It’s an odd function that is continuous everywhere but differentiable nowhere. I’ll explain what that means shortly. Here’s the function: Here: The following two sections explain what it means to … Continue reading →

Draw a recursive overlapping snowflake fractal in C#

Posted on February 25, 2016 by Rod Stephens

The example Draw a recursive snowflake fractal in C# explains how to use an iterator and a generator to draw a snowflake fractal. This example uses the same technique with the initiator and generator shown in the second and … Continue reading →
