PyGeM is an open source Python package which allows to easily parametrize and deform 3D object described by CAD files or meshes. It implements several morphing techniques such as free form deformation, radial basis function interpolation, inverse distance weighting. Due its versatility in dealing with different file formats it particularly suited for researchers practitioners both academia indu...

Image morphing, which is a 2D imaging technique, allows smooth transition between images. However, a limitation of existing image morphing techniques is the lack of user interaction. Another limitation is that shape warping often causes distortion due to barycentric mapping. In this paper, we present a novel 3D morphological technique to address these problems. A new concept of relief occlusion...

This paper presents a morphing model of vector geographical data based on Fourier transformation. This model involves three main steps. They are conversion from vector data to Fourier series, generation of intermediate function by combination of the two Fourier series concerning a large scale and a small scale, and reverse conversion from combination function to vector data. By mirror processin...

The voice morphing process presented in this paper is based on the observation that, in many styles of music, it is often desirable for a backing vocalist to blend his or her timbre with that of the lead vocalist when the two voices are singing the same phonetic material concurrently. This paper proposes a novel application of recent morphing research for use with a source backing vocal and a t...

This paper presents a new compatible remeshing approach, by morphing with Radial Basis Function based on approximate geodesic distance (G-RBF) followed by a mesh optimization to generate compatible meshes efficiently while approximating the input target geometry accurately. To test the proposed approach, a prototype is implemented to clone expressions onto the personalized 3D face model. A PCA ...

In this paper, we present a new technique for 3D shape morphing using strain fields. Strain is an important geometric quantity used in mechanics to describe the deformation extent of objects. We use it to analyze and control deformation in morphing. Using the position vector field, the strain field between source and target shapes can be obtain. This strain field is then interpolated between ze...

This work addresses the computation of free-energy differences between protein conformations by using morphing (i.e., transformation) of a source conformation into a target conformation. To enhance the morphing procedure, we employ permutations of atoms; we transform atom n in the source conformation into atom σ(n) in the target conformation rather than directly transforming atom n into atom n....

We describe a method based on convex combinations for morphing corresponding pairs of tilings in IR. It is shown that the method always yields a valid morph when the boundary polygons are identical, unlike the standard linear morph.
