You provide an image as input. The app tries to find the most optimal shape that can be drawn to maximize the similarity between the target image and the drawn image. It repeats this process, adding one shape at a time. Using this process, the program can recreate a photo with surprisingly few shapes.

This project was originally inspired by the popular and excellent work of Roger Johansson - Genetic Programming: Evolution of Mona Lisa. Since seeing that article when it was quite new, I've tinkered with this problem here and there over the years. But only now am I satisfied with my results.

The core is written in Go and is open source. A native macOS app is also available in the App Store, providing a nice UI on top of the engine as well as some additional features like "drawing mode." To date, this has been my most successful paid app.

Go has an excellent set of image packages, but what do you do when you want to render 2D graphics? The golang freetype library implements nice anti-aliased rendering of paths, but is primarily for drawing text. So I built gg on top of it to provide a nice, general purpose 2D graphics API inspired by Cairo.

Features

• Anti-aliased rendering
• Fill and stroke paths
• Draw images and text
• Built-in word wrapping
• Line caps, joins, dashes
• Gradients and patterns
• Transformation matrix
• Push and pop context state
• Clipping regions

This was my submission in the /r/proceduralgeneration monthly challenge. I used several excellent third party libraries...

• cairo for rendering
• colour for color interpolation
• noise for simplex noise
• Pillow for saving debug images of noise layers
• pyhull for delaunay triangulation
• Shapely for all kinds of 2D geometry operations

This code provides an interesting API for constructing tilings of regular polygons. It can also render the dual tilings.

Efficiently create AllRGB images that target an input image. The input must be 4096x4096px. The output will also be 4096x4096px and will contain all 16,777,216 distinct RGB values once and only once.

See allrgb.com for details on the concept.

Explore the mathematical beauty of fractals and create stunning fractal art with Scale. Scale is fast and a pleasure to use. It was designed from the ground up to be intuitive and user-friendly.

Piet Mondrian was a Dutch painter. His paintings with orthogonal lines and rectangular splashes of primary colors on white backgrounds are very recognizable. I wondered what it would take to programmatically generate Mondrian-esque images. Here's what I came up with.
