The Story Behind the Image
This is a ceramic bowl used in a Japanese tea ceremony. The image was inspired by a photograph in a book titled "Minimum" by John Pawson.
The bowl illustrates a complex mathematical shape with complex texturing. The basic bowl was formed by combining mathematical functions for cylinders, spheres and toruses. The shape was then modified by adding low freequency geometric noise to create the undulations in the basic surface and adding a higher frequency geometric noice to create the small bumbs on the surface.
The texture was created by first writing a function that generated and layered four different textures. Each of these subtextures differ in the scale of the noise patterns. This creates variations in the pigments that range from tenths of an inch to inches. This function was invoked three times with three different total amounts of dark pigment. The final texture was created by arranging the three pigment levels vertically so that the center area of the bowl had more dark pigment than the top and bottom ends.
