Paul de Casteljau

from Wikipedia, the free encyclopedia

Paul de Faget de Casteljau (born November 19, 1930 in Besançon ) is a French physicist and mathematician .

Life

Paul de Faget de Casteljau studied mathematics and physics at the École normal supérieure in Paris , did his military service in the Algerian war and began in 1958 as a physicist at Citroën , in the Groupe Détermination Mathématique des Carrosseries . The French Patent Office from there were Institut national de la propriété industrielle (INPI) de Casteljaus basic documents modeling of curves and surfaces with splines deposited. At the end of the 1980s, he succeeded in combining the Bézier and B-spline technology through Blossoming . He has been retired since the beginning of the 1990s, where he last worked on quaternions and metric geometry.

meaning

As a physicist at Citroën, De Casteljau developed the De Casteljau algorithm named after him for the approximate description of Bézier curves with polygonal lines .
