The Code Fractal geometry in nature and digital animation

Marcus du Sautoy describes how fractal geometry can be used to describe natural objects, and how it is used in digital animation. Trees use the simple rule of trying to maximize surface area, and this is something that can be simulated mathematically to give a very realistic result. Mandelbrot explored this fractal property of infinite complexity in his work, which ...
