Abstract

This paper presents a sculptured solid modeling system founded upon dynamic Catmull-Clark subdivision-based solids of arbitrary topology. Our primary contribution is that we integrate the geometry of sculptured free-form solids with the powerful physics-based modeling framework by augmenting pure geometric entities with material properties such as mass, damping, and stiffness distributions and with physical behaviors such as elasticity, plasticity, and natural deformation under external forces. Our novel dynamic model of free-form solids frees users from having to deal with low-level control point operations and permits them to interact with subdivision-based virtual clay in a more natural and intuitive fashion via "forces." 1. Introduction To date, the vast majority of popular solid modeling approaches as well as commonly-used solid modeling systems are built upon the following geometric foundations
