A Ridge-Lines-Based Interface for Triangle Mesh Deforming
Abstract—Most surface in computer graphics are
represented as triangle meshes. Techniques for interactive
deformation of triangle meshes are a fundamental important
part in a host of applications. Most traditional approaches to
the deformation have emphasized precise control over the
models by a man made selection of a set of control point.
However, they are often cumbersome and non-intuitive for the
non-expert users. In this paper, we present a system for
deforming triangle meshes which is easy to use and need less
interaction. Our method computes the high order curvature
derivatives describing the salient features of meshes, such as the
ridge lines. By interacting with the ridge lines as the handle to
control the deformation, the user can implicitly and intuitively
control the deformation of all meshes. We demonstrate that our
system can make the surface manipulated and modified by
preserving the geometric details.
Index Terms—Ridge line, laplacian deformations, differential
