Sierpinski sieve generator tool What is a sierpinski sieve generator?
This tool draws Sierpinski sieves, also known as Sierpinski triangles. A Sierpinski triangle is a fractal structure that has the shape of an equilateral triangle. Each triangle in this structure is divided into smaller equilateral triangles with every iteration. At the moment we allow up to 13 iterations because drawing 14th iteration takes too long. With this tool you can customize Sierpinski gasket's size and looks. You can set the width and height of the fractal, change the background, foreground and fill color, change triangle's width and change padding around the drawing. Mathabulous!
Sierpinski sieve generator examples Click to use
Create a 4th Order Sierpinsky Triangle
This example iterates Sierpinsky algorithm for 4 iterations and draws it on a 400 by 400 pixel canvas. It uses three different colors to draw it - white for triangles' border, brown for background and red for inner triangles.

Draw a Non-filled Sierpinsky Sieve
This example uses only two colors to generate a Sierpinski sieve fractal. It disables color-filling option that fills inner triangles and as a result you get just the outline of all triangles.
