This video morphing and turning the space rocks was created not by the sculpture or modeling in the usual manner, but by using the fractal mathematics. (Video Link).
One of the principles of fractal geometry is self-similarity, where large forms are composed of smaller and smaller components that share the same geometry. This is a principle of design in nature as rock shapes, forms clouds and forms of branching. digital graphics powered Fractal provide a tool to build worlds for animation and computer games.
The video was Julius Horsthuis rendered in 3D Mandelbulb, with music by Maurice Horsthuis.
