Abstract: | In this paper, we present a material-aware mesh deformation method using a sketching interface. Guided by user-specified material
properties, our method can deform the surface mesh in a non-uniform way, while previous deformation techniques are mainly
designed for uniform materials. The non-uniform deformation is achieved by material-dependent gradient field manipulation
and Poisson-based reconstruction. Compared with previous material-oblivious deformation techniques, our method supplies better
control of the deformation process and can generate more realistic results. We propose a novel detail representation that
transforms geometric details between successive surface levels as a combination of dihedral angles and barycentric coordinates.
This detail representation is similarity-invariant and fully compatible with material properties. Based on these two methods,
we implement a multi-resolution deformation tool, allowing the user to edit a mesh inside a hierarchy in a material-aware
manner. We demonstrate the effectiveness and robustness of our methods by several examples with real-world data. |
