Abstract Isotopic Approximation of Implicit Curves and Surfaces (2008)
Implicit surfaces are defined as the zero set of a function F: R 3 → R. Although several algorithms exist for generating piecewise linear approximations, most of them are based on a userdefined...
Part of deliverable: WP-III/D4 Site: RuG Month: 24 (2008)
Project co-funded by the European Commission within FP6 (2002–2006) under contract nr. IST-006413 We present an implementation of the isotopic meshing algorithm for implicit surfaces. The...

3 Partially supported by the IST Programme of the EU as a Shared-cost RTD (FET Open) Project under Contract No IST-006413 (ACS – Algorithms for Complex Shapes) Given points in convex position in...
Isotopic approximation of implicit curves and surfaces (2004)
Implicit surfaces are defined as the zero set of a function F: R 3 → R. Although several algorithms exist for generating piecewise linear approximations, most of them are based on a user-defined...
Contour generators of evolving implicit surfaces (2003)
Simon Plantinga, Simon Plantinga, Gert Vegter, Gert Vegter
The contour generator is an important visibility feature of a smooth object seen under parallel projection. It is the curve on the surface which seperates front-facing regions from back-facing...
