From Mandelbulb: Mandelbulb is a three-dimensional analogue of the Mandelbrot set. A few of the supported 3D fractals: Mandelbulb, Mandelbox, BulbBox, JuliaBulb, Menger Sponge, Quaternion, Trigonometric, Hypercomplex, and Iterated Function Systems (IFS). All of these can be combined into infinite variations with the ability to hybridize different formulas together. Features include 3D navigator with tools to see how close the camera is to the fractal surface, complex 3D shading: hard shadows, 3 modes of ambient occlusion, depth of field, reflections, fog, glow, primitive objects, and water, lights can be manually or randomly placed, volumetric lighting available, camera animation: Keyframe and mouse controlled flight, keyframe animation of all parameters, camera lenses: three-point projection, fisheye, and equirectangular projection, distance estimation algorithm to reduce render times and artifacts of ray marching, and low memory mode to render images larger than 16,000 x 16,000 pixels.
