Curve implicitization using moving lines
WebSep 1, 2024 · The implicitization of rational plane curves have been extensively studied. The method of moving lines introduced by Sederberg and Chen in 1995 [1], and then extended further three years later in the foundational paper [2] with the additional concept of -basis, gave a powerful solution to this problem.

Web5.4.2.4 Implicitization. As we have discussed in Sect. 5.4.1 , point/implicit curve intersection problem is conceptually very simple. Therefore it is natural to consider conversion of the curve equation from a parametric form to an implicit form. Sederberg et al.
