Implicit modeling by metamorphosis of 2d shapes

Abstract

Nowadays, there is a lack of existing practical modeling tools suitable for specification of free-form implicit shapes. In this paper, we propose a new interpolation technique supplemented by interactive tools aimed at shape modeling by feature preserving metamorphosis of two-dimensional implicit shapes. The metamorphosis is controlled by global parameters and a set of correspondence vectors that are drawn directly to the scene. The underlying environment is the XISL package for definition and manipulation of implicit objects, which offers additional modeling and rendering possibilities.
