EXTRUSION OF 1D IMPLICIT PROFILES: THEORY AND FIRST APPLICATION
Loïc Barthe, Véronique Gaildrat, René Caubet · International Journal of Shape Modeling · 2001
This paper presents a new interpretation of the general definition of the binary blending operator of implicit modeling. Instead of considering the operator as a composition of potential functions or as a function defined in the combined primitives metric, we propose to consider it as an implicit curve extruded in an implicit extrusion field. An implicit extrusion field is a 2D space for which each coordinate is a potential field.
