Larger image from small image
I didn't invent the algorithm idea, I got it from my maths teacher in 2011 or 2012.
This is a console-like use of openFrameworks. The program takes as arguments input and output image filenames. (on linux I run make && ./bin/texture-path <input_image> <output_image> [--show-seam])
The algorithm is explained in the code file main.cpp.
The algorithm was used in one of my first coding projects in 2012-2013. In 2019 I made a much better short uncommented version, with Qt. Today (December 22nd 2024) ChatGPT o1 translated it successfully for openFrameworks on first try and added explanations/comments.
