Approximate Implicitization of Space Curves

Abstract: The process of implicitization generates an implicit representation of a curve or surface from a given parametric one. This process is potentially interesting for applications in Computer Aided Design, where the robustness and efficiency of intersection algorithm can be improved by simultaneously considering implicit and parametric representations. This paper gives an brief survey of the existing techniques for approximate implicitization of hyper surfaces. In addition it describes a framework for the approxim… Show more

“…Today, there are direct [7,25] and iterative techniques [1]. An idea used in approximate implicitization is to use successively larger supports, starting with a quite small set and extending it so as to reach the exact implicit support.…”

“…, and prepare the input file for ResPol: [1,3], [2,2], [3,1], [2,3], [3,2], [3,3]] Alternatively, in the second line we could explicitly specify the support points that define the projection of N (R), by their order in the set of the third line: 7 6 14 | 0 7 13. These are exponents of the terms of F 0 , F 1 , F 2 whose coefficient contains the implicit variables x 0 , x 1 , x 2 .…”
