In this gallery I tried to simulate some animals, plants or famous characters through a single polynomial equation.
The difficulty lies mainly in two points: firts, imagine the object by means of “easy” forms (when I say “easy” I mean those forms that can be simulated through polynomials of low degree), and second, describe the object mathematically. First point is important because of the limited capacity of the program. Finally, it is also important a proper use of the zoom.
All the images have been done through Surfer2008 or Surfer 1.4.0 Debian package, just with polynomials.
