Altered Qualia is described as 'Evolve takes an input image and reproduces it using shapes of various colors and transparencies. It uses a simulated annealing-like optimization algorithm based on the great work of Roger Alsing' and is an app in the Development category. There are four alternatives to Altered Qualia for Linux, Mac, Online / Web-based, Self-Hosted solutions and Windows. The best alternative is Primitive, which is both free and Open Source. Other great apps like Altered Qualia are Primitive for macOS (Paid), Genetic Art (Free, Open Source) and Shapeme (Free, Open Source).
Based on the author's open-source Primitive project, Primitive for macOS adds a super intuitive interface to make it dead easy to process images, recreating them with primitive shapes like triangles, rectangles and bezier curves.
Inspired by Roger Alsing's great idea, Shapeme uses SDL to evolve images with simulated annealing. HOW IT WORKS It takes a reference image (a PNG file). It starts with a set of random triangles and/or circles.
