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.
