A projective invariant generalization of the de Casteljau algorithm
A projective invariant generalization of the de Casteljau algorithm is described by using the cross ratio and an auxiliary line We describe the implicit form of the section conics obtained by the algorithm proposed in this paper Finally we show how to construct specific conic sections using this approach (C) 2010 Elsevier Ltd All rights reserved
