Visions of Symmetry
370 pages 438 illus., hardcover
|Rinus Roelofs began a formal study of applied mathematics and after four years, changed direction and completed an art degree, concentrating in sculpture. Like Escher, he likes to work out ideas with hand-drawn sketches, but then uses computer software to turn those sketches into views of three-dimensional works that can be animated, printed as pictures, or have their data interpreted by special "3-D printers" into real models in wax or plastic. Just as Escher was fascinated by interwoven layers of grids of circles and of hexagons (see pages 87,92-93, 226, 232), Roelofs also has explored such grids and the questions they suggest (see his article "Not the tiles, but the joints..."). One exploration led to an unusual sculpture. He began with a grid of three layers of interwoven reg-ular hexagons, then shifted the layers a bit so that the pattern of a regular octahedron would fit the symmetry of the interlaced grid.
|He then cut out and folded the pattern into its three-dimensional form, wrapping the interlaced grid around the polyhedron. From that model, he noticed that the bands outlining the hexagons all connected continuously, and if the white of the paper were to disappear, the interlaced bands could actually be realized as the interweaving of just one layer of the hexagons. Finally, he used the software Rhinoceros to turn his paper model into a pleasing sculpture that was cast in bronze.
In his 1958 book Regelmatige vlakverdeling (The Regular Division of the Plane) Escher opens by lamenting his artistic isolation in pursuing his fascination with symmetry:
Why am I the only one fascinated by it?...
Today, Escher is not alone. His work has infected others with the same enthusiasm, and they walk not only the paths he trod, but, like him, discover new paths and experience fresh delights.
