C. Auguste Dupin of their around-the-world adventure. A Pierre Dupin appears in Universal Pictures' 1932 horror-mystery film "Murders in the Rue Morgue". "The Mystery of Marie Roget" was also filmed in 1942. Dupin (played by Joseph Cotten) is a character in the 1951 Fletcher Markle film "The Man with a Cloak". Dupin's true identity is revealed at the end of the film to be Poe himself. In the comic series "Batman Confidential", the creation of Batman's crime-solving super-computer which is linked to Interpol, FBI, and CIA databases is introduced. Commonly known as the "Bat Computer," it is originally nicknamed "Dupin," after Batman's "hero."
Dupin cyclide also used to refer to a more general class of quartic surfaces which are important in the theory of separation of variables for the Laplace equation in three dimensions. Dupin cyclides were investigated not only by Dupin, but also by A. Cayley und J.C. Maxwell. Today, Dupin cylides are used in computer-aided design (CAD), because cyclide patches have rational representations and are suitable for blending canal surfaces (cylinder, cones, tori, and others). There are several equivalent definitions of Dupin cyclides. In formula_1, they can be defined as the images under any inversion of tori, cylinders and double cones. This shows
