Fourier

 

The Fourier transform involves approximating a closed loop with a number of spinning circles joined together called epicycles. The more epicycles used, the closer the approximate path is to the original. This works in a similar way to a spirograph.

Support:

You can either draw your own paths with your finger or upload a photo of a silhouette to the app. On an iPad you can also draw with an Apple Pencil for extra precision. Remember that any line you draw needs to be in a closed loop or path may not be transformed as intended.

 

When uploading your own pictures, make sure that they have a high contrast ratio and are a black silhouette on a white background. This will help the algorithm pick out the intended path to transform. Sometimes the algorithm will fail on photos that have a large file size or do not have a defined path to transform. If this happens, the photo icon will turn to a cross for a second to indicate that there has been an error. The larger the file size uploaded and the more epicycles used to approximate the path will cause the transformation process to take longer, although it will almost always take less than a second.
