2d strain field morphing

Morphing Based on Strain Field Interpolation

In morphing, we would like one shape is smoothly deformed to another shape. But how can we ensure the deformation process is smooth? And how to define deformation? In fact, deformation problem has long been studied in mechics and a strong tool "Strain" is used to define shape deformation. Integrated with the finite element method, in this paper, we proposed a new 2D morphing method based on strain field interpolation. What's more, we present a easy way to create 2D consistent triangle mesh. More...

Three Dimensional Strain Field Morphing

We extend the strain field interpolation method into 3D morphing. Strain is used to define the deformation extent and is interpolated to get the strain of intermediate frames. The intermediate shapes are calculated the interpolated strain. More...

Convex Combination Spherical Parameterization Using Spherical Coordinates

In this paper, a new spherical parameterization method for closed and genus-zero mesh is presented. Compared to other convex combination spherical parameterization method using Cartesian coordinates, this approach lowers the nonlinear extent, and the solution time decreases greatly. Moreover, several degenerate cases under Cartesian coordinates are avoided.

Skeleton-Based Shape Deformation using Simplex Transformations

This paper presents a novel skeleton-based method for deforming meshes, based on an approximate skeleton. The major difference from previous skeleton-based methods is that they used the skeleton to control movement of vertices, whereas we use it to control the simplices defining the model. Our method also needs no vertex weights defined on the bones, which can be tedious to choose in previous methods. What's more, we present a segmentation approach to determine the correspondence between mesh simplices and the bones.
