Zusammenfassung:
Harmonic surface deformation is a well-known geometric modeling method that
creates plausible deformations in an interactive manner. However, this method
is susceptible to artifacts, in particular close to the deformation handles.
These artifacts often correlate with strong gradients of the deformation
energy.In this work, we propose a novel formulation of harmonic surface
deformation, which incorporates a regularization of the deformation energy. To
do so, we build on and extend a recently introduced generic linear
regularization approach. It can be expressed as a change of norm for the linear
optimization problem, i.e., the regularization is baked into the optimization.
This minimizes the implementation complexity and has only a small impact on
runtime. Our results show that a moderate use of regularization suppresses many
deformation artifacts common to the well-known harmonic surface deformation
method, without introducing new artifacts.
