Description
Convert an SVG file or Image into a Fourier epicycle squiggle!
Draw a closed loop with your finger or Apple Pencil or upload a picture or of a silhouette or SVG file and I will transform it into a Fourier epicycle squiggle using the complex Fourier series!
Features:
• Import SVG files
• Import Images of silhouettes
• Copy the Fourier equation coefficients (initial angle and radius)
• Save pictures of your squiggles to your photo library
• Change the thickness and colour of the outline
• Use up to 500 epicycles to approximate outlines
Learn the Maths behind the complex Fourier series on 3Blue1Brown's YouTube channel.
What’s New
Version 1.1
You can now import and squigglify SVG files, copy the Fourier equation coefficients (initial angle and radius), save pictures of your squiggles to your photo library, change the thickness and colour of the outline, use up to 500 epicycles to approximate outlines, and much more!
Ratings and Reviews
What does it do?
I don't understand what this app is supposed to do. Is it just a drawing program? I cannot find any action buttons, such as "Create Fourier transform." The description says "I will create..." -- is that "I" the app or the developer?
Wish there was a numerical output
I wish there could be an option to see the coefficients (radius and initial angle) for each vector in the result.
Developer Response ,
Hello, thanks for your feedback! The new update now allows you to copy the Fourier coefficients in the equation result including the radius, initial angle, and angular velocity in csv format. Jack
