The unsigned p-Willmore functional introduced in the work of Mondino [2011] generalizes important geometric functionals, which measure the area and Willmore energy of immersed surfaces. Presently, techniques from the work of Dziuk [2008] are adapted to ...

We present a discrete theory for modeling developable surfaces as quadrilateral meshes satisfying simple angle constraints. The basis of our model is a lesser-known characterization of developable surfaces as manifolds that can be parameterized through ...

There are various techniques for deforming three-dimensional objects in existing computer-aided design CAD systems. To maintain user-specified constraints in the deformation of a parametric and feature-based model is a new challenge in deformation ...

We propose a novel formulation to express the attachment of a polygonal surface to a skeleton using purely linear terms. This enables to simultaneously adapt the pose and shape of an articulated model in an efficient way. Our work is motivated by the ...

A shape constrained Laplacian mesh deformation approach is introduced for interactive editing of mesh sequences. This allows low-level constraints, such as foot or hand contact, to be imposed while preserving the natural dynamics of the captured ...

In the process of numerical simulation, Finite Element Analysis (FEA) is commonly used for product design optimization. The product model has to be modified according to its associated optimization result obtained based on analysis, and the mesh model ...

This paper introduces an innovative computational design tool used to edit architectural geometry by addressing the problem of irregular vertices. An irregular vertex is a special kind of vertex, which is connected with less or more edges than regular ...

There are various techniques for deforming three-dimensional objects in existing CAD systems. To maintain some user specified constraints in a deformation of a parametric and feature-based model is a new aspect in deformation modeling. This paper ...

Man-made objects are largely dominated by a few typical features that carry special characteristics and engineered meanings. State-of-the-art deformation tools fall short at preserving such characteristic features and global structure. We introduce ...

In recent years we have witnessed a large interest in surface deformation techniques. This has been a reaction that can be attributed to the ability to develop techniques which are detail-preserving. Space deformation techniques, on the other hand, ...

Motion is the center of attention in many applications of computer graphics. Skeletal motion for articulated characters can be processed and altered in a variety of ways to increase the versatility of each motion clip. However, analogous techniques have ...

This survey reviews the recent advances in linear variational mesh deformation techniques. These methods were developed for editing detailed high-resolution meshes, like those produced by scanning real-world objects. The challenge of manipulating such ...

In this paper, we present a multigrid technique for efficiently deforming large surface and volume meshes. We show that a previous least-squares formulation for distortion minimization reduces to a Laplacian system on a general graph structure for which ...

We present an interactive system that lets a user move and deform a two-dimensional shape without manually establishing a skeleton or freeform deformation (FFD) domain beforehand. The shape is represented by a triangle mesh and the user moves several ...

We introduce a rigid motion invariant mesh representation based on discrete forms defined on the mesh. The reconstruction of mesh geometry from this representation requires solving two sparse linear systems that arise from the discrete forms: the first ...
