Shape preserving mesh deformation

ACM SIGGRAPH 2004 Sketches on - SIGGRAPH '04, 2004
Deformation is the process of interactively transforming the surface of a model in response to some control mechanism. It is commonly used for model editing and animation. Typically, mesh deformation techniques require global knowledge of the model structure (such as a skeleton) and are quite time consuming.

Improved Mesh Deformation

2013
An improved, robust, error reducing CFD-mesh deformation module for the parallel simulation environment FlowSimulator is presented. The mesh deformation method is based on radial basis function interpolation for the surface- and volume- mesh nodes combined with a group-weighting and displacement-blending approach.

Skeleton‐based Variational Mesh Deformations

Computer Graphics Forum, 2007
Abstract In this paper, a new free‐form shape deformation approach is proposed. We combine a skeleton‐based mesh deformation technique with discrete differential coordinates in order to create natural‐looking global shape deformations. Given a triangle mesh, we first extract a skeletal mesh, a two‐sided Voronoibased approximation of the medial axis ...

Strain Imaging with a Deformable Mesh

Ultrasonic Imaging, 1999
Ultrasonic strain imaging has drawn much attention recently because of its ability to noninvasively provide information on spatial variation of the elastic properties of soft tissues. Traditionally, local strain is estimated by scaling and cross correlating pre-and postcompression ultrasound echo fields.

Deformable Volumetric Simplex Meshes

2008
In this article, two possible ways to build volumetric meshes of simplexes are described. One structure uses the crystalline organization of carbon atoms in diamond and it is used to simulate the deformation under internal pressure of a container. The second structure is in layers and it is used to simulate human body tissues that could be cut. We also

Dynamic meshes for deformable surfaces

ACM SIGGRAPH 2006 Research posters on - SIGGRAPH '06, 2006
Mesh adaptation is an area of intense research because of its importance. However, most of the work in this area has concentrated on adapted meshes for static models. The problem of creating dynamic meshes for deformable objects received less attention up to now.

Skeleton based 3D mesh deformation

2007 6th International Conference on Information, Communications & Signal Processing, 2007
In this paper a novel and intuitive method for the interactive deformation of 3D meshes is proposed. This method is based on skeleton. After a region of the model to be deformed is selected and several reference points are specified, a skeleton is created implicitly and automatically through the reference points and the screen. Then the vertices in the

Subspace gradient domain mesh deformation

ACM SIGGRAPH 2006 Papers on - SIGGRAPH '06, 2006
In this paper we present a general framework for performing constrained mesh deformation tasks with gradient domain techniques. We present a gradient domain technique that works well with a wide variety of linear and nonlinear constraints. The constraints we introduce include the nonlinear volume constraint for volume preservation, the nonlinear ...

Mesh deformation with hard constraints

International Symposium on Signals, Circuits and Systems ISSCS2013, 2013
In this paper we tackle the issue of 3D mesh deformation when hard constraints of warping are imposed by user or application. First, we propose a review of the most salient methods existent in the technical literature. Then we retain for a more detailed analysis only some variants of Laplacian coordinates and Radial Basis Functions techniques that ...

Preserving form features in interactive mesh deformation

Computer-Aided Design, 2006
Interactive mesh editing techniques that preserve discrete differential properties are promising to support the design of mechanical parts such as automobile sheet metal panels. However, existing methods lack the ability to manipulate form-features and hard constraints, which are common in engineering applications.
