Self-similar, recursive forms with endless detail.
A personal site collecting algorithm experiments and visual toys. Fractals, reaction–diffusion, chaos, the n-body problem, boids, the travelling salesman problem, Voronoi diagrams and more can be set in motion and explored in the browser.
A huge archive of mathematical and physical simulation images by a researcher at École polytechnique in France, with more than ten thousand pictures and animations grouped by theme — real numbers, fractals, quantum physics, astronomy and more. The site is old-fashioned and easy to get lost in, but it is still being updated.
Articles on computer graphics, mathematics, shaders and fractals. Its explanations of signed distance functions and raymarching are standard references for anyone drawing shapes with equations.
A personal site with a vast collection of notes and examples on geometry, fractals, curves and surfaces, visualisation and dome projection. Equations sit alongside code, making it a long-standing reference for makers.
A book by Daniel Shiffman on simulating natural systems with code. It covers physics, particles, autonomous agents, cellular automata, fractals and genetic algorithms with p5.js, and is freely readable online.
