Sierpinski arrowhead curve generator tool
What is a sierpinski arrowhead curve generator?

This tool draws Sierpinski arrowhead curves. A Sierpinski arrowhead curve is a continuous fractal curve that in iterations limit case produces a Sierpinski triangle. At the moment we allow up to 13 iterations because drawing 14th iteration takes too long. With this tool, you can customize how the arrowhead curve looks and its size. You can set the width and height of the triangle, change the background and foreground color, set curve's width and change curve's padding. Soon you'll also be able to change curve's orientation. Mathabulous!

Draw a Pink Sierpinski Arrowhead Curve

This example iterates Sierpinski arrowhead curve for 6 iterations on a 400x400 background, changes it to pink and foreground to white.

**Required options**

Sierpinski arrowhead curve's width.

Sierpinski arrowhead curve's height.

The order (iterations) of the curve.

Arrowhead's background color.

Arrowhead's line color.

Sierpinski arrowhead curve's thickness.

Padding around the width and height.

Generate a Stretched Arrowhead Curve

This example uses a non-proportional size for the arrowhead curve and draws it on a 300x250 background using 4 generations. It uses nice contrasting colors to give the curve a pretty look. It also sets padding to 10px.

**Required options**

Sierpinski arrowhead curve's width.

Sierpinski arrowhead curve's height.

The order (iterations) of the curve.

Arrowhead's background color.

Arrowhead's line color.

Sierpinski arrowhead curve's thickness.

Padding around the width and height.

Generate a Sierpinsky Triangle

This example generates a full-blown Sierpinski triangle. As the order of the curve gets bigger, the curve becomes indistinguishable from a triangle. Here we set iterations to 9 to demonstrate it.

**Required options**

Sierpinski arrowhead curve's width.

Sierpinski arrowhead curve's height.

The order (iterations) of the curve.

Arrowhead's background color.

Arrowhead's line color.

Sierpinski arrowhead curve's thickness.

Padding around the width and height.
