Feature-Preserving Interactive Mesh Deformation

Abstract

Aesthetic surfaces usually consist of free-form surface regions and form-feature regions. When interactive deformation techniques are applied to such surfaces, they are required to satisfy the shapes of form-features exactly and free-form regions approximately. This paper proposes a new framework for managing hard and soft constraints. We solve the combination of hard and soft constraints using the Lagrange multiplier method and sparse linear matrix solvers.
