Interactive modeling method using deformable quadrics and set-theoretic operations

Abstract

A method for creating functionally based objects using deformable quadrics and set-theoretic operations is proposed. Interactive editing and modeling are described as ways to increase realism. The decoration technique allows the user to draw directly on 3D objects. Interactive modeling of the shape of geometric objects defined by perturbation functions is considered. Such objects are characterized by a high degree of smoothness and are described by a small number of functions. They are easy to deform and create shapes like modeling from plasticine.
