Non-Euclidean geometry caused a re-examination of the teaching of geometry based on Euclid's Elements. This curriculum issue was hotly debated at the time and was even the subject of a book, "Euclid and his Modern Rivals", written by Charles Lutwidge Dodgson (1832–1898) better known as Lewis Carroll, the author of "Alice in Wonderland". In analytic geometry a plane is described with Cartesian coordinates : "C" = { ("x,y") : "x", "y" ∈ ℝ }. The points are sometimes identified with complex numbers where ε ∈ { –1, 0, 1}. The Euclidean plane corresponds to the case since the modulus of is given
Neil Dodgson he worked on image resampling supervised by Neil Wiseman and graduating with a PhD in 1992. Dodgson worked for many years on stereoscopic 3D displays, conducting research principally into autostereoscopic methods. He has contributed to several surveys of the field and has been on the committee of the annual Stereoscopic Displays and Applications conference since 2000, co-chairing the conference four times. With Malcolm Sabin, Dodgson has worked on subdivision surfaces since 2000. Dodgson's team produced the NURBS-compatible subdivision method in 2009. Dodgson has supervised almost twenty research students for PhDs. Dodgson also takes an interest in abstract art. Neil Dodgson
