要旨:
We present an interactive method for applying deformations to a
surface mesh while preserving its global shape and local properties.
Two surface editing scenarios are discussed, which conceptually
differ in the specification of deformations:
Either interpolation constraints are imposed explicitly, e.g., by
dragging a subset of vertices, or, deformation of a reference
surface is mimicked.
The contribution of this paper is a novel approach for interpolation
of local deformations over the manifold and for efficiently
establishing correspondence to a reference surface from only few
pairs of markers.
As a general tool for both scenarios, a harmonic field is
constructed to guide the interpolation of constraints and to find
correspondence required for deformation transfer.
We show that our approach fits nicely in a unified mathematical
framework, where the same type of linear operator is applied in all
phases, and how this approach can be used to create an intuitive and
interactive editing tool.
